Go ahead and call me noob but I really dont know much about timing and pcm tuning. I know just enough to understand that getting a smaller pulley (And tune it accordingly) is probably the last mod I want to do. If I understand it correctly yall are saying that on my setup (3" ZZP downpipe, open cone intake, cooler plugs, 180* Tstat and proper tune) the better choice is a 3.6" pulley rather than the 3.4"?
