Need to do more to your exhaust before you open up the intake more. You have to give the air a place to go before you open it up to let more in.

yea i was thinkin that,it only makes sense.so i guess i ill start with either a headers package or the zzp dp,crossover,plog combo.i heard youll get more out of it gettin headers but zzp is cheaper.man choices choices.

Decide where you want to go. I finally decided I'm going to go N/A for the time being, and any mods I do now will support a turbo later. So, I'm going for Plog and coated cross-over for exhaust for now (along with other stuff). Already have a DP and catback.

If you ever plan to go turbo, ditch headers. They don't work with turbos, except the DP portion of the TOGs is used as part of the ZZP turbo kit.

okay,so l'll go the zzp route.i'm kind of hesitant bout gettin the reprogrammed pcm,does it really enhance your car that much?
