think the 2.8 and 4lber be ok ?

Might be a little aggressive. I ran a 3.0/4lb and had to upgrade to a billet tensioner to control belt slip. On 3.0/4lb setup, I saw 22psi with long tubes as well. I just say why away from the 2lb because it’s hardly any bigger than stock but your sacrificing the support the stock caged lower offers. So that’s why I say if you’re gonna do, go big. I tried a 2.80/4lb before the thump tensioner and it was instantly slipping the belt.

interesting, im running the roush tensioner im kinda in a pinch on pulley because of dyno day but im assuming a 2.8/2# lower will yield same boost as 3.0/4# lower

Did you try to follow the write up for factory prime in the how to section?

I know that way still uses the fpdm as that’s how I did mine.
