Tuned this bad a*z 67 nova last week for a new customer that was recomended to us from another shop. There were some wiring issues as usual with every custom build that comes in. We wired the fans and ac compressor through the terminator so that everything would perform seamlessly. After adding a fuel pressure sensor and putting the correct map sensor in, it was ready for a tune. I have to say in the end, this 429" TSP engine and 4l65 made for a great driver!

Beautiful third gen camaro powered by a 6.2l 495hp LS and run with a holley terminator x. Car came in with some serious driveability issues. The gentleman that owned the car was very frustrated. I assured him that I would be able to make the run how it should and that this project could finally reach completion. In just a few short hours I had this beauty of a camaro running flawlessly. Its always satisfying to see somebodys dream come to life and be a part of making somebody happy. Thank you all for the continued support and God bless!

This nice c10 showed up last week for a tune on an LS 6.0 run by a holley terminator. After looking the truck over I realized it had a few issues. Fuel pressure was incorrect due to a cheap LS swap filter/regulator which is something I see alot. The throttle only opened 1/4 of the way due to the most ineresting throttle cable setup I have ever seen. And lastly once I got full throttle we were out of fuel pump and injector. After a new fuel pump, fuel pressure regulator, and remaking the throttle cable we were able to get a good base tune in until we can get the truck back in for an intake and injector upgrade. Some pics in the comments of what I found lol. Thank you all for your continued support!!

Beautiful 70 Chevelle SS we just went over for a new customer. recomended this customer to come see me to wrap some things up that were not finished properly during the initial build. After some wiring repair and a couple issues remedied she is performing flawlessly and back out the road where she belongs. Love what I do and working with friends and other businesses to come together and give people something they can truely enjoy.

There is alot going on here as the weather warms up and the season is getting started. Have a carb to holley terminator swap on on the OG cutlass, LS swap for my brother in law, and continued progress on the 69 Buick Gran Sport thats getting a twin turbo LS. Looking forward to hearing some internal combustion happen and that sweet smell of e85!!

Beautiful low mile 02 ws6 in for header gaskets and a computer recalibration. These were the best looking f body cars of their time and this car is a true survivor! It may not be an 800hp killer but it soothes the soul. Some days are definitely better than others!

Picked up a family members car to finish the ls swap he started. All of the basics are done. Needs some finish wiring, plumbing, and the J&T touch! We are shooting to have this car wrapped up in about a weeks time and deliver it back home. More pics and details of the diy swap will be posted over the next week.
