I had my car tuned by Bill, the Tuning doctor:

and I cant begin to tell you the difference on how the car runs after all the mods i have done to the car.
After getting work done and tuned by TTP, the car has run like crap and I was not a happy camper.
But since bill tuned the car, damn the car runs smooth as can be with the head cam package I have making the power I still wanted.
I drove almost hundred miles each way twice to drop it off and pick it up and it was well worth the trip!
