So I'm finally switching to a bigger innercooler, bigger piping and changing to a speed density to run a vta bov Ooooh yeah with a new intake also, then getting it tuned....but my question is if any if you gear heads (no pun intended) could tell me what kind of increase i can be expecting as far as hp,tq and the way my car drives id really appreciate

 

what mods do u have now?

 

Header, fp white, tbe, fuel pump, hks 272',s exedy carbon twin disk, mishimoto radiator, and slight tune

 

you will gain more from a proper tune. i wouldnt bother going with bigger piping just stick with 2.5". you will gain power but you need a tune to get it.

 

That's the size piping I'm going with...3 inch just seems to big. Plus doing the short rout I'm going to gain 40 hp from this while process after the tuner of course

 

always take what you read on here about gains and divide it in half, thats what ive learned in my 6 years of evo ownership.

 

Haha very true but nobody told me this its just what I'm expecting hopefully I'm not to far off from the bullseye
