I put it on this morning with the one step colder ngk plugs, decided to gap them at .38 and start there. Car seems fine, defineltly more responsive. Hits 15psi instantly and starts creeping up, not sure what total boost is yet since i didnt stay it in long past 5500 (morning traffic)

Stock plugs were ngk as well and they were gapped a tight .35 if anyone wanted to know that.

Im hoping to see 17-18 psi up top, what do you guys think?

 

Welcome to the 2.8 club I loved seeing 15 psi instantly all the time.

 

You should end up with about 17psi. Bro you have to dyno that with AFR and see what the heck your IDC is from 5,500-7,000rpms. Congratulations bro. She will be a beast.

 

nice.

 

I have access to the gm scanner that they do the stage 2 flash with, i used that when i did the stage 2 then went to the dyno and they were dead on to each other, car was fat in the mid range and up top so im sure its plenty safe. I will do both again real soon for you guys. AS long as its not above 12.0-12.2 i wont panic but anything more will make me uncomfortable. I like to be mid 11'5's with my forced induction cars

 

Welcome to the 2.8" club, and you'll love the fatter torque curve. Let me know how the .38 gap works out. I had mine at .040 and my car didn't like them.

 

be careful on that 2.8 . Better check your IDC after 6100 rpms. anyways congrats and enjoy
