Hi I'm wondering if I could safely run a 3.4" pulley on my 2002 GTP.
Here are the following mods:
•3" zzp downpipe w/cat
•zzp powerlog front manifold
•u bend delete
•Wizaired CAI
•colder spark plugs
•Procom tune (next month)
What do you guys think? Should I also invest in a kr sensor and boost gauge? Thanks.
