2.9+

though 3.0 is what the safe recomendation is ...

I would say 3.0, that way you dont need to replace the belt and tensioner pully...

ok so a 3.0. what kinda of difference should i see with that? i already orderd teh aem cai, it should be coming in this week.

you will notice 15lbs over stock 12.5, boost comes on instantly, and that intake is going to make youre little M62 cry loud as hell.

15-15.5 psi....... roughly 20-25 hp, 30-35 with intake and pully, you will like it........ trust me

don't you need to chang the plugs if you go with a smaller pully?

Yeah I would get a range colder plugs. South Florida Pulley Headquarters sells them.
