Would installing upper and lower IC pipes affect the A/F without tuning?I don't have a wideband so any thoughts would be great.I know i won't see the full benefit of the pipes as far as power without tuning,im just wondering if it would be safe to drive the car and hit boost without knowing what the A/F is at WOT.

 

I believe the AFRs would be effected by the Wider open IC pipes, but I am not sure.

Regardless, better to be safe then sorry and not do many WOT pulls until its tuned

 

They are slightly not enough to be a problem. I have a wideband and such and have watched each mod. I did full bolt ons (full 3in no cat, big IC, full IC piping, intake) all I had to do to correct a/f was a 255 pump. The only mod I had to tune for was the hks 272/272 cams.

Run the piping it might help your oem tune its far to rich. Just remeber a tune is the best power adder.

 

Thanks guys.
Anyone else have any input?

 

Any vendors want to chime in.
