So I ordered a 3.6 MPS from zzp last week showed up this weekend and the pulley says 3.5 do I dare install it or just contact them to get the 3.6...I have done lots of reading and there is so much varied opinion on this so lets see what everyone thinks lol...car is currently WB tuned by my friend with HPT has SD headers and DIY intake I have 0 kr...Thoughts?
You have all the flow mods and you are scanning, I don't see an issue.
I just put a 3.5 on mine Friday and the difference is noticeable (noise and feel)
