anybody know bout the press on pulley from zzp. im assuming this is a direct bolt on part for the factory supercharger. i think its a 2.85 inch pulley. to small??? i really hate to be at that point where its possibly to small for stage 1 injectors and stage 1-2 tune

 

way too small you will need 60 lb injectors (you could get away with 42's but you would be pushing it so why bother) your also gonna need a custom tune and i would say some exhaust mods , if you want to change your pulley get a 3.1 modular pulley system and you would be legit on stock tune and stock injectors , you will also need a stage 2 belt , if i were you i would just look into getting stage 2 its like 550 plus install (200-300)

 

Its what I have. Bought it along time ago its probably on the edge of where you want to be with the stage tune but its working for me

 

whats the a/f tune for the stage 1-2 kits
