et's with an ATI ProCharger
 

Anybody got some et's with a procharger? Trying to decide between H/c or ATI ProCharger

Dyno After GWP Stage II ATI Procharger D-1SC and MAC Headers/Y-Pipe

My first verson of the GWP Stage II was sort of like a better tune-able Stage I that was supersafe. Performance results are about what you'd get from the base ATI unit, but the FMU can be a headache.

Not being satisfied, I stepped up to the original intent of the GWP Stage II (minus the head/cam factor) with a smaller pulley, larger injectors and headers and ran the 10.98 @ 125.83 MPH on stock internals.

Hope that helps...

Get both!

MMS is putting out high 500rwhp cars with their SC packages and with their H/C included, they are putting up mid 600rwhp numbers! If I had to pick one I would go with the SC.
