FIRST POST HAHAHA
Ok, I just bought a 97 GTP from a family member, mods that were already done to it by my uncle were 3.4 pulley, Custom FWI, 3in DP, 3in to 2.5in dual dynamax's (no cat/res or u-bend), 180 T-Stat, MSD coils, Taylor 8mm Wires, 1 range colder spark plugs (i was told), i might be forgetting something but i think i got everything.
i am doing some what of a tune-up to the car because its had about 6k miles put on it in 5 years, new engine oil/filter, new S/C oil, Spark Plugs, Smaller S/C belt (stock belt w/ 3.4 right now).
NOW my question is with these mods are the 1 range colder plugs ok or do i need to go 2 ranges colder? I read almost all of bluegtp91 3800 Modding Sticky but didnt really see the answer i was looking for so thats why im askin for help...
