I know that a re-tune is recommended to get the most, but will it be safe to drive? Has anyone had any issues?
I tried to find answers in the forum but I only found this: https://www.ft86club.com/forums/show...exhaust+retune
Just wanted to make sure.
Thanks a bunch! |
I would recommend a retune. You will be having less back pressure and possibly make more boost with the higher flowing exhaust (not tasing about major change, but some more).
Why chance it? given you are adding boost to a factory NA engine, best be safe.
