i currently have a comptech sc aftercooled set up on my ap1 and im running the ap2 pulley on it with a greddy ultimate ecu tuned and injectors i have 300WHP now in the summer im thinking of getting a 10psi pulley and a new tune, the questions i have is should i keep the greddy ultimate ecu? will it be reliable? any suggestions?

 

i plan to do the same don't see a problem have the same setup with meth injection

 

If you have someone that's tuned it at 300whp reliably, then there are no limitations. The unit is more then capable of maximizing your Supercharger. Run it to 15psi/3" pulley and call it good. I am upgrading my blower to a 1200 and maximizing this 450whp+ with my Greddy Ult.

 

Awesome guys right now it is tuned and reliable I'm aiming for 400whp I hope it works out

 

I don't think you'll hit 400whp with a 10psi pulley. You're gonna need a 12-13 psi pulley to get to the 400s

 

For 400whp with that sc kit go straight for the 14-15 psi pulley. That should get you around there.

 

Yes, the 3" Pulley is what you want if your going for 400whp on a Comptech kit. 10psi will get you half way there, 350whp average.
