This is what we mean by supporting mods:
Well start with the 3.4 pulley as it usually starts the majority of these questions. Below you will find a list of supporting mods that should be in place prior to installing that 3.4. Can you get away with less? Possibly. Have people gotten away with less? Yes. Do you want to take the chance? Enough said.
1. PCM- standard v 1.0 will suffice at this level.
2. CAI/FWI- Cold Air Intake/ Fenderwell Intake, you can build your own or purchase one from a vendor.
3. Ported Exhaust Manifolds/ Headers/ ZZP Powerlog- your choice, at this level Pems or the Powerlog are fine, if your planning on further modding later you will need headers, only you know your budget.
4. 3" Downpipe- Crushbendt which most exhaust shops will do is unadvised, preferable to purchase an aftermarket from one of the vendors.
5. 1-2 Heat range colder plugs. i.e Autolite 104's or equivelent gapped in the .050-.055 range
6. Ubend delete- just after the cat, most exhaust shops will be able to remove this and put in a straight pipe.
