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.

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.

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. 

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.
