it wasn't just the launch, if i remember correctly you burned it through the shifts too. plus, you used to keep your foot on the clutch, because you didn't know it was bad. maybe you're just doing something that is bad for the car, without even knowing it. it's very possible. not knocking by the way, just saying it's very possible.
usmcfieldmp - 30mins is enough to cool her off again depending on the temps outside usually, if you do back to back runs, or with a 5-10 min or less gap, then your iat2s increase pretty quick.
cobaltvenomss - the posters and shirts aren't going to make a difference but im sure you knew that. I would try and do a 3rd gear only run and see how you do. That way neither of you are shifting, so the driver mod is taken out of the aspect. If you win, then you know its your driving. If he still wins then you know somethings up or you are somehow heat soaking way to much, which shouldn't be the case.

If you are still under warranty... take it in and ask them to Reflash it for you. Just tell them it is running weird and you want to get the tune checked. Don't mention racing of course.
Get on the interstate late at night and do a 3rd and 4th gear pull. 4th gear was where I STEAMROLLED a stock one on the interstate.

buy a scan gauge venom, that way you can monitor your IAT and knock retard and such.

WHOA... delete what I was gonna say.
Check your Intercooler pump. Turn on your car and make sure the coolant is flowing.
Mine died last year... it'll seriously **** your car up when it comes to going fast.

Strange. Maybe you suck at driving. Haha. I'm not sure other than that. I murdered stock LSJ's when I was on the Stg2 tune with a 2.8"... absolutely murdered.
Who was in your car? Anything in your trunk?
What about his car? Any passengers?
Weight makes a BIG difference. Just having my 120lbs fiance in the car is a difference of winning by 3 cars or winning by 1/2 a car against my friends SRT-8 Jeep.

maybe his car is like mine. magical 07 cobalt lol
IF, you need a new one and aren't under warranty... then order one of these from Ford Racing. Its the Exact same pump. It'll cost you $89 on eBay from Ford. It'll cost you $400 from Chevy.

One other possibility, when I but the Gm honed manifold with my stock downpipe I lost power, put on a custom downpipe, and gained it back plus more. The downpipe with stock manifold might not work well together.

your car is going to have higher iat2s then his right off the bat because of the smaller pulley. As soon as you guys both smash the gas, your iat2s are slowly creeping up compared to his. By the time you guys hit 80 i would bet that yours are about 10degrees higher, and by the time you hit 110 they are probably 20degrees higher.
It may not seem like a lot but you would be shocked at what temps can do to power. I would look into a methanol kit, a heat exchanger, dual pass etc. Cooling mods help a ton, especially when you live in a hot a$$ state like texas.
It will feel like a whole new car to you.

What plugs/gap do you have...when I gapped too low the car ran really shitty, worse than with the 2 step iridiums but I shouldn't have been running those in the first place. Do 1 step colder (autolite 3922) at .035-.036 and you should be good. Idk...there's a ton of things it could be...if it were me I'd check my boost gauge to make sure everything is kosher

damn.. lol the IRL or SS/SC to do the best aginst me was a stock pulley HPtuned with intake and full GMPP exhaust.. he ONLY lost by about 1 1/2 car's by the end of third.. i however pulled away like he wasnt movin a 2.85 pulley on 43.5 #er's custom tune NO cat with a solid trans mount from 40 roll's when i was stage 2 factory exhaust except for a muffler swap axel back.. i think it's a combo of each car/driver .. and how each driver respectively treat's said car..

Something is wrong then because I have the stage 2 with airbox mod (stock everything else) and the car rips. I can pin it in 2nd and the tires will break loose. Never did that when I was stock, lol.
