I am relatively new to moding, i do know what each does, but not sure in what order or which first. any ways all seem like good ideas so ill definitley look into tyhose suggestions.
Best way is to start with small bolt on "basics"
These are easy to install / removable / make a difference
Intake - self explanitory
Test pipe - mid part of exhaust. opens up air flow and bolts on to stock or future aftermarket exhausts
BOV / BPV - no more leaking boost with the stock bpv
shifter bushings / short shifter - better shifting
sway bars / springs - tighten up handling
Intercooler - Do your research or start with a tmic. The resale is good so you can upgrade to a FMIC later.
Cobb AP - easy flash tuner
Those are a list of bolt ons. Any of them alone will make a difference. Those are all easily removable. My advice would be to start with those before you invest in stuff that is more "permanant" such as up'd turbos, fuel pumps, FMIC, downpipes. Not to say they arent removable but its much more difficult.
