my 07 is going in next week for the whipple HO kit, i seen on another post when running 8 psi they had an off road h pipe, but when they bumped up to 11 they switched back to the stock h pipe, will i be ok with the off road h at 11 psi ?

isnt the HO 10 psi?
but you should be ok just have it tuned good. my a/f w/ o/r x pipe was a little lean, but a tune fixed it.

You should be fine but get the car tuned (dyno) for safety and baseline numbers!

Edit: didn't realize the O/R part.....get it tuned!

I've heard it will run lean without a custom tune. Someone from whipple stated that in another forum. The whipple tune is designed for a car with cats.

I would never ever go any forced induction route with out putting her on the rollers for a proper tune, caned tunes are grewt for mild upgrades but when you go serious power you need it done right.
