Hey ......i own a 2002 GTP i want to add a intercooler to my car but am worried that i dont have all the supporting mods to get the most power i can.



Mods so far:

Downpipe

cat back

3.4 pulley

8.8mm wires

FWI

ported gen III

ported exhaust manifolds

zz pcm



I just baught a stage 3 intercooler with ported llower intake....i know my car needs a tune and was wondering if any other mods need to be done to get the most out of the set up im going to run.....keep in mind head work is next year so no rockers etc....





any help would be more than beneficial
