Does anyone on here have a 2.8, predator tune and K&N FIPK? I was wondering what kind of numbers you are putting down with this combo and stock exhaust? I am just curious what I should expect before I get the car dynoed.
The stock exhaust is a HUGE cork in that setup of yours. You would pick up about 20+ RWHP if you swapped it out. I would bet you will be under 450 on a dynojet with that combo. The Predator pulley tune sucks balls too, expect to not have a very good looking A/F ratio. Hopefully your dyno operator can tune for Predators because you are going to need it. Good luck.
