I know that Tech2Drew states his 7 psi pulley is safe on the engine using the stock injectors with no tuning, but can anyone here verify that with their own cars? Who here is actually running the upgraded pulley without switching out the injectors and getting engine mangement with NO problems?

I am striving for at least the 300whp mark with the Comptech, but from what I've read many people have come short of it with stock psi. I'm just looking for anyone's personal experience with this. Thanks for any help you can provide!

 

I have a 4" (8lb without AC) pulley, but there was no way I was doing that with just the Comptech FPR.

I went E-manage, SARD regulator and 440cc Injectors. Now I've upgraded to AEM so I can go the next step.
