I am to the point now where I am honestly wanting to get a different tune....and yes I have a budget tune, but it never worked right from the start. I think I got on Vince's nerves trying to fix my issue but when everyone else is getting 22+lbs of boost and I can't even get 15lbs, I get a little pissed.

BNRacing can you help me?

BTW I was forced to pay $50 to get the car to operate correctly in warm weather, it was throwing a MAF code when it was 80* or higher, luckily we got that fixed (I do appreciate this) but I still don't understand why I can't get a tune that allows me to get the boost everyone else does.
The automatic HHR SS seems to have this problem when you try to run over GMS1 power levels. I'm not sure why but we see this often. Trifecta's fix for it has been to offer a GMS1 type tune for it that works on the stock MAP sensors. Email Vince and ask for it and it will fix you right up.
