There are many factors that affect a dyno run, things like one dyno is designed differently than another, the experience and skill of the dyno operator.
Humidity, air temp, and altitude are not a factor. These are corrected for by the SAE stations included in the dynos.
Aside from possible a noob dyno operator and the difference of dyno design, you RW numbers seem low. Many report that they are getting around 360-370 max RWHP on a completely stock '11 GT with stock tune.
To account for this I have a couple of speculations:
1) Your rear gear is the base 3.31:1 gear. I presume that going to 3.55:1 would increase your completely stock car w/ stock tune to around 360 max RWHP
2) You car is still brand new and not been fully broken in yet. The internal friction of the engine, tranny, and other still tight parts in the rest of the drive train could be putting a significant drag to affect your RWHP.
These are just my speculations, because I do not know who many miles you ha on your car when you took them to the dyno and I do not know what rear gear you have in your diff.

Plus being that it's an automatic, I only have 3.15 gears.

Since I got rained out at the track last night. Decided to put the car back on the dyno and let BBR play with some of the TiVCT and Cam Angle tables to see if they could get more power.... and sure as hell... THEY DID
Stock 350 rwhp / 332 rwtq
BBR Xtreme Tune 375 rwhp / 354 rwtq
Remember, this is a BONE STOCK AUTOMATIC. So 25 rwhp / 22 rwtq gains on a bone stock car is pretty dang good I think.

I'm looking forward to getting my tuner and custom tunes to load them up onto my auto. I hate the feeling of pushing the gas down sometimes and just getting nothing for a while. Looking forward to really feeling a linear relationship soon.
