does anyone have one on there car with an intake and a exshaust. was there a big diffrence. and what was your horsepower gain . and what times did you run at the track

 

I personally don't, however you're not going to net big gains by tweaking your ECU after a couple of bolt ons. Wait unitl you've got I/H/E, JDM IM, bored out TB, new cams and valve springs, etc. You only want to VAFC type tuning after you've finished a good bit of modding.

 

the vafc2 is an excellent mod, but i would also wait for a few more mods before i put it in

 

save your money...get hondata for your type-s, its pretty much the mandatory mod for NA Type S'
