Right now Im up in the air on what size MPS to use. Whether it be a 3.5 or 3.4 It should show too much KR with either with the supporting mods I have in place. The Hi-flow and possible flowmasters will wait till later. But other than that, I think Id be okay running a 3.4. Ideas? Also if anyone has the size numbers or can point me in the direction of part numbers for the corresponding belt PN or sizes.

im getting 2-4*KR average and spikes of 6 with this setup and the 3.4.... PEM'* cant wait much longer

i think youll be ok with a 3.4. if you had a intense pcm, id say it might be iffy but u should be good with the dhp

Ive run 2-3* of KR with my 3.4, with the stock PCM, only FWI , plugs and high flow cat.

You should be ok with a 3.4.

KR wth a 3.4? Go PEM guys. Mine disappeared.

Gutted box, K&N drop in..and now pem'* and a HF cat. All is well in the world.
