TRUE OF FALSE Power Loss After Intake and Exhaust Setup

Bshields22

Hey guys,

I have been seeing multiple people say different things about the end result of an intake and exhaust mod. Thought I would try and get to the bottom line

1. Does a Stillen (or any other good brand name) Intake and Exhaust cause a power loss? I would use the qtr mile and/or 0-60 to crosscheck the "claimed" power gain or loss.

2. Since I hear more "powerloss" stories then gain stories, say there is a power loss, what needs to be tuned for the power loss to surpass the stock performance? Typical costs and success rate?

Also how does that tune effect the rest of the car? Would it cause other issues down the road since other components in the car are not built around the new calculation?

Thanks for all the help!!
