on all my turbo cars i have always used a apexi super air fuel controller.[saf-c] when i did not have ems...so why cant we use saf-c and bigger injectors???i would guess that would work way better than the maf trans...you can adjust you fuel in % and you can go 50% more fues or 50% less fuel....and tune it way better on the dyno...or better yet if you have the inovative wide band you can just drive around and tune it and save your money...

 

as it turns out, piggy backs, such as the s-afc, and greddy's e-manage have limited functionality on our cars. the maf-t setup that intense racing sells is your best bet for now. that is until someone cracks the pcm and comes up with a flash or a chip....or just wait for gm to flash it.
