Tune after Cutouts installed???

Definitive · 02-21-2010, 01:48 AM

Hey guys,
Doing some reaserch on getting exhaust cutouts. Ive now been told a custom tune is a must after and also that you wouldent need tune for them.

What do you guys think? Any experience? Any technical explanations(i.e. either AFR doesnt change)?

Thanks for any help.

They're post cat cut out's so you shouldn't need any tune for more power. Now if you put them pre-cat, then you may get some extra power with them. The Porsche guys like to put them in Pre-cats.

You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
