Default FAST 90 and Tune

I just had my heads and cam installed and tuned last week. I'm getting my FAST 90/90 this weekend. Would i need a retune?? or could i just install it and be on my way....?

I would think you will need a little touching up to the tune. You are feeding the car more air with the bigger intake and TB. To be safe I would get one. Maybe the shop that did the work will hook you up since they just tuned it.

It might need some A/F adjustments after that, or maybe the fuel trim, but nothing 20 minutes on Edit won't cure.

It needs a re-tune. My car was considerably off after a Fast 90/90 install. The problem is exemplified when you have a dead on tune for the old setup, and then you throw on a new intake.

I agree just to be safe.
