Customer Testimonials
Johanna Testimonial
“20,000 miles and a year and a half since I modded my Hellcat Redeye Challenger and had Curt remotely tune it with his Flex package. The car runs great and drives regularly on both the street and strip, with recent maintenance including oil changes and new spark plugs. Besides the great tune, I’d always recommend Curt’s business if solely for how helpful he has been and the quick response time always thru email. Dusterhoff Racing is a great company, and happy I chose them to tune my car. Thanks for sending my lady the sticker recently, Curt 😂.”
Michael S. Testimonial
“The tuning process was excellent overall. I haven’t had any issues with my own shop cars or customer vehicles. The sales department is top-notch as well—no matter how small or simple your question may be, you’ll always get an answer.
The first car Curt tuned for me was my 2020 Dodge Charger Scat Pack. It was a full bolt-on E85 setup—nothing too crazy—but I didn’t get to enjoy it much since I was constantly taking it apart in my pursuit of more speed. Eventually, I decided to upgrade to a 2018 Dodge Charger Hellcat, and the first thing we did was install the 997E Package. The results were incredible—so much so that people didn’t believe the car was only running an upper/lower pulley combo on E85! It performed exceptionally well, hitting a 4.xx-second 60-130 MPH time with ease.
At the end of the day, Dusterhoff Racing is an amazing team. Whether you have a simple bolt-on daily driver or a full-blown race car, as long as it’s a Gen 3 HEMI, they’ve got you covered. Their dedication to customer service and performance goes above and beyond expectations.”
BJ H. Testimonial
“My buddy and I recently installed an upper pulley, injectors, thermostat, and a few other upgrades on his 2018 Charger Hellcat. For tuning, we went through Curt—and let me tell you, I’ve worked with a fair number of tuners over the years, and Curt is by far the best!
He’s down-to-earth, straightforward, and a true professional in this field. The tune he provided, along with the revisions he made almost in real-time through email and phone calls, was absolutely perfect. The car runs fantastic, all thanks to you, Curt!
I can’t wait for the next step—and you can bet I’ll be coming back to work with you again!”
John M Testimonial
“Dusterhoff Racing has taken my daughter’s Scat Pack with the DT605 package and pushed it into the 11s in the ¼ mile—all with simple bolt-ons and remote tuning. The tuning process was smooth, easy, and completely painless.
As for my own car, my Hellcat Challenger (non-Redeye, a.k.a. the “Jailcat”) runs the DT1077E package, and we’ve continued to build from there. Dusterhoff did not disappoint—this car has laid down an 8.88 at 155 MPH in the ¼ mile on a stock motor!
In my opinion, and based on my experience, Dusterhoff Racing is the best in the business..”
Tom Beasley Onsite Install Testimonial
“After picking up my brand-new Redeye, I knew I wanted more—and the DT937 Flex Fuel Package from Dusterhoff Racing delivered. I drove 700 miles just to have it installed, and it was worth every minute. The flex-fuel setup makes switching between E85 and 93 effortless, and the power gains? Night and day.

What kind of builds do we take in?
We operate a small, high-quality-focused shop with a single dedicated technician. This intentional approach allows us to maintain an exceptional level of precision and attention to detail in every build we take on. Because of this, we are selective about the jobs we accept.
Our primary focus is on stock vehicles receiving our performance packages, parts, and upgrades. If you have a previously modified vehicle or your own parts, we may be able to take on the work, but it depends entirely on our workload at the time, so don’t count on it.
If you're interested in getting on our list, reach out, and we’ll follow up if an opening becomes available.
