Thank you very much ima take your word for it and begin putting everything back.

Ive been researching the MAF and it semi makes sense that it might be getting pegged. I seen on the camaro forums guys talking about a weak and a strong MAF too, maybe this autozone MAF was poorly built.

Any thoughts on this?

Do you have a wideband like mentioned before? If not not you are asking to blow up your motor because you have no idea what the air fuel is

yeah i have the wide band on, but its in a good okay range for now, i think the maf is throwing it out of whack.

But i placed my order on the GM PMAS MAF, it was a little pricey, but hopefully itll fix the situation, if not onto putting stock components back on

Motor is way way rich, I can tell just by hearing it. Your MAF is not working correctly. Find a new tuner that will tune it 2bar SD (I can help you if you have hptuners). No need to keep the MAF on these trucks with boost, more trouble than its worth. MAFs have their place, just not with this.

Yeah GMT-800's it's SD if you want boost. The GMT-900's can use the MAF just fine with a 2 bar map sensor for boost.

I think with the amount of money spent on the dyno tune, trips there, and buying a new MAF i could have purchased HP tuners, and conservatively tuned it myself.

A refund doesnt sound like a bad idea right now.

I missed where this was a 2011, thought it was the one in your sig. Same thing applies though, it's way rich. Your stock MAF should be ok but you need a 2bar sensor in there. Your issues are tune related.
