08 stock LM7 with Procharger 1 bar map tune?

Can I boost 7 psi and add fuel without a 2bar map sensor?

So far is working well, and Ltrims are -8 at wot

But not sure if I can improve the tune with the 2 bar sensor !

Should not be an issue. Flaco tunes boosted trucks all the time using the MAF. He suggested that I upgrade my MAF to one of the Corvette card type sensors, can't remember if it was the LS9 card or not, though.

I'm on the berry now, but as soon I get home I post a scan log for you.

Fot the way I look at it, I wont be needing bigger injectors or anything else.

Not to trash the procharger, but sure is not what I spected, never the less, it moves better !
