FAQ

  • What does Dusterhoff Racing do?

    Dusterhoff Racing is a late-model performance company, based out of North Georgia. We specialize in Gen 3 Hemi Performance. We provide parts, tuning, build advice, power packages, and installation services. 

  • How does remote tuning work?

    To get the remote tuning process started, we need a Pre Tuning Form filled out. This form describes all the vehicle’s modifications in detail and we use this information to work up the tuning invoice and build a base file. Please make sure to fill the form out as completely as possible. If we don’t have good information here we can’t properly create the tune file for your vehicle. Once the invoice is paid, we can then schedule a tuning appointment on the tuning calendar or send the tune to the tuning department for them to get started. If the tuning invoice is not paid, you do not get a tuning appointment. All tuning must be prepaid. Until your appointment is confirmed, you do not have an appointment.  Appointments are confirmed via Google Calendar invite that is sent to you that you must ‘accept’ to hold your time. Tuning is performed remotely via email and timely responses are needed to ensure your vehicle is done on time. 

    Once the tuning department receives your tuning request, they will email you with a start file and request for a log. Tuning will be completed via email back and forth until the vehicle is done. You will need to perform logs of your car in multiple scenarios including wot log.

  • What are the appointment options?

    Tuning appointments are offered at specific times or we can work your tune a little at a time in the order received over the course of a few days to a week. We have tuning appointments at 9AM and 1PM EST Tuesdays through Thursdays, and 9AM EST on Fridays only. If you choose not to do an appointment, and instead do a little bit at a time, please keep in mind that our typical email reply time is 1-2 business days. 

  • What if I need to reschedule? 

    If you need to reschedule your tuning appointment, please reach out to us with at least 48 hours notice via email or phone call. If you reach out to us inside of the 48 hour window, there will be a $75 surcharge added to your invoice that will need to get paid in order to get back on the tuning calendar. Our tuning calendar is full, and when you no show for an appointment it costs us money and hurts our other customer who have been waiting to get their vehicle tuned. If you are more than an hour late to your appointment, you lose your appointment slot, will be charged a $75 surcharge that needs to be paid prior to scheduling another appointment, and get added back to the tuning calendar. 

  • What kind of response/turn-around time should I expect?

    Our normal business hours are Mon-Fri 9 AM to 5 PM EST. We do not work weekends or evenings.  Our typical response time if you do not have an appointment is 1-3 business days. If you email Friday afternoon it may be Tuesday or Wednesday before you receive a response depending on work load.  We strive to have as fast of response times as possible but at this time we can not guarantee responses any quicker than this, especially during our busy season.

    We apologize if this turnaround time doesn’t work for you, we want to make sure we set expectations upfront for all customers. If this doesn’t work for what your needs are, we understand and encourage you to seek out other options although these response times are on the shorter side of the spectrum as far as the industry as a whole. 

  • What is required for Remote Tuning? What will I need? 

    We tune using HP Tuners ONLY. In order for the process to smoothly, the equipment you will need is a HP Tuners Interface, and Credits. For 2015+ vehicles, you will need your PCM unlocked for HP Tuners. For 2018+ vehicles, you will need a HP Smartaccess cable. You will need a windows capable laptop, the HP Tuners software (available at: https://www.hptuners.com/downloads/ ), wifi / internet, and your vehicle. We also offer tuning with tdn and rtd’s as well. For this you will need a smart phone, tdn app and HPTuners interface.

    We will need datalogging done on your end to complete tuning unless we are doing a load and go file. You as the customer are expected to datalog your vehicle with the thorough instructions provided to you. Without datalogging, we cannot complete the tune process for your vehicle as there is no way around this.

    We cannot bench flash the PCMs, or mail them to you already tuned. 

    The remote tuning process is time time-consuming and unique process to every customer. Some vehicles may only take one or two revisions while others may take many more.  You will be required to drive the vehicle and log it in different conditions including but not limited to wide open throttle. When asked for pulls, we are very specific with our instructions, and need those instructions followed precisely. Do not go rogue with your pulls if we are not asking for it. Only make one pull unless otherwise requested. If you do not follow the instructions as given, there is a possibility you can hurt the vehicle. We know by the datalogs you send what you are doing to the car, so please follow all instructions to the best of your ability. If you need assistance, please reach out to us. 

  • My car is on E85, do I need to test the fuel?

    Yes, if your vehicle is being tuned on e85 you need to have a tester to test the alcohol content.  Alcohol content can vary wildly across the country depending on the time of year.  If you own a vehicle that is going to run on E85, we strongly encourage you to purchase a tester and regularly test your fuel to ensure the safety of your engine.

FAQ

  • What if I have a mechanical issue?

    Since we did not install the parts on your vehicle, we cannot assist you in diagnosing your mechanical issues at no charge. The service that you have paid us for is calibrating (tuning) your vehicle, not diagnosing and fixing mechanical problems. If we get into tuning your vehicle and there is a mechanical issue, we can assist in diagnosing it but charge a fee of $75/hr for said service. Since many times we run into situations where we believe the vehicle has a mechanical issue but the customer believes it is calibration-related, we will refund any diagnostic fees if we find the issue to be a calibration-related problem. If you purchased your parts through us, we will assist as much as possible in diagnosing any mechanical issue with the parts. As much as we wish we could help fix every issue on every vehicle, it is often inefficient for us to do so remotely not to mention it is outside of the scope of work we were originally paid to do.

  • Are your tune files locked?

    YES. We lock our tune files. We have thousands of hours of R&D to develop the intricate understanding of the platform that we have today. You will not be able to edit the tune files that we send you. This is nothing personal, we simply are protecting our company, business, and information.  Unfortunately, theft of information is rampant in the performance tuning market and we are doing our best to protect the information we have worked hard to gain. We also ask that you please not share our information with others.

  • I added parts since last time it was tuned, do I need a new tune or revision?

    Yes, please reach out to us and we can get you a revised file after your invoice is paid. You will need to fill out an additional tuning form for the new modifications to the car. Please fill out this form to the best of your ability. Revisions vary in price depending on how much tuning work is involved, i.e. adding longtube headers will not cost as much as new cam or fuel system. 

  • What are your terms of service?

    REMOTE TUNING CANCELLATIONS, MISSED APPOINTMENTS, AND REFUNDS

    Remote tuning can be refunded up until a base file has been provided. Refunds will be made for purchase amount, less any merchant transaction fees.  If a start up/base tune was provided, there are no refunds on tuning. 

    We have tuning appointments at 9AM and 1PM EST Tuesdays through Thursdays, and 9AM EST on Fridays only. If you choose not to do an appointment, and instead do a little bit at a time, please keep in mind that our typical email reply time is 1-2 business days. 

    If you need to reschedule your tuning appointment, please reach out to us with at least 48 hours notice via email or phone call.

    After Hours Support Policy

    All after hours support requests are to be directed to [email protected]. Please include your name, reason for request, and best number to reach you at

    Once an email is received and someone is available to assist, we will send an invoice to be paid for two (2) hours of support. Once paid, we’ll reach out either via phone or email to assist. After Hours support is $175/hr, with a two hour minimum.  All time that exceeds the initial two hours will be billed at the $175/hr rounded to the nearest half hour.

    Terms of Service and Support 

    Our normal business hours are Mon-Fri 9 AM to 5 PM EST. We do not work weekends or evenings.  Our typical response time if you do not have an appointment is 1-3 business days.

    We lock our tune files. We have thousands of hours of R&D to develop the intricate understanding of the platform that we have today. You will not be able to edit the tune files that we send you. We also consider all information contained in our tune files to be proprietary and confidential. Do not share any information contained within a tune file with anyone.

    If you have a mechanical issue in tuning it is your responsibility to diagnose and fix said issue. At times we may offer complimentary diag support when a customer has bought both parts and tuning from us but that is at our discretion. If you need additional diagnosis support, we can assist remotely for $75 an hour.

    All tuning customers will receive support for their tune for 120 day from the delivery of the start up/base tune.  It is important that our customers are all receiving the same standard of support.  This modification allows us to ensure that everyone is being supported in a meaningful way and has the time to load, test and confirm that their tune is dialed in to their liking.  All tunes that remain “open” will be considered complete and delivered at 121 days regardless of expressed customer sign off.  We reserve the right to extend this policy on a case by case basis but in general, 120 days from sending of the base file is our support timeline.
