Unfortunatly the dealer has no ability to adjust this as they can only load stock GM cals. If GM comes out with a leaner cal due to multiple customer complaints of low power (they have done this in the past) then your dealer could load that updated tune, but otherwise it is what it is.
If you go to your dealer and tell them the guy from PCMFORLESS or the Camaro5 board for that matter says you are losing 25 to 30 HP because the factory tune is rich and the timing is weak they just aren't going to take you serious because they just don't understand the inner workings of the ECM themselves.
I think if enough of you guys go in with compaints of low power GM may consider tweaking the tune some to get the air fuels at least into the mid 11's and add a bit of timing. Back in the late 90's a bunch of Mustang Cobra guys compained of lack of power and Ford changed all of their intake manifolds and I think exhaust manifolds to raise the power. Changing the ECM cal is much easier and less expensive.

What would you do if you were me? Is this car acceptable according to GM marketing?
Should I just get a tune and be done with it?
If I can't get in the low 5s to 60, and under 5 in the fall, I will just get a tune and be done with GM all together.
Am I being unreasonable? I don't know what the hell to think. I sure wasn't expecting this when I ordered this thing. Right now I'm sooooooo wishing I would have gotten the LS3.
And before anyone decides to flame me, I'm not talking about anyone but ME. If I would have got the stick, I wouldn't be having this issue. Sure, the car is strong but not like it should be and I don't think it's wrong to expect to get what's advertised. I love the new Camaro. Just not mine.
Most of the L99s seem fine but how many have tested them. Performance wise or diagnosticly?
