This past weekend we were tuning out at Goodguys autocross in Loveland Colorado. We had a great time and took home some hardware for both class wins and winning both of our shootouts. We had fastest times all weekend overall. Josh won the prox class and Andrew and Karen came in first and second in the Corvette class. All in all a very successful weekend.

I failed to get many pictures of this beast so ill just have to describe it. This vr4 is a super clean build with a built engine, dog box trans and a fp3586 turbo. Its all controlled by a haltech Ecu, almost every sensor imaginable, on E85. Its blows my mind as few of these that were built new that I have tuned 6 of them just this year and have been tuning them almost since they were new.

Do we work on pickups? Of course. These ranged from some maintenance to tuning a twin turbo setup. Through the years we have probably built most every kind of build and combination in all makes of pickups. Reach out if you have a project for yours in mind and we can likely share a similar build we have done in the last 26+years we have been open.

Just a few of the cars we have worked on the last two weeks. Some got mechanical upgrades such as fuel injection, some got debugged from previous problems and some got full Dyno tunes. We can handle it all.

67 Camaro was in this morning for a tune on its LS3. Sometimes vehicles come in for a tune and need some work before they are ready. We worked through a few problems to insure a great outcome when we finished tuning. In the end it helps make for a comfortable driver with power and great manners.

Yesterday we had this camaro in to straighten out a really bad tune. He was told he needed a ecu among other things and in the long run we just did a tune with no parts changes and he is back to driving and starting great and makes great power.
