Throttle body change

[forkliftman79]

Quick question, if I change the stock throttle body to a larger one or ported one do I have to flash tune the car or is it self calibrating. When I installed my Vararm it said the car would adjust itself. Any feedback would be a great help.

Ported I think you will be ok w/o a tune if you go to a larger size like a 90mm you will not get the full potential w/o a tune. With the TB being such a small increase in performance by itself you might look at a larger intake and headers at the same time.

If you are going to make it breath in better you want to make is exhale better also.

Thanks, I already have the ram air intake, and SLP long tube headers, high flow cats and piping and mufflers. I guess ported is the way I will go then.
