05 GT vs 05 Vette

OK I know...maybe not what your thinking, but my older bro bought an 05 vette, and we wer talking about a friendly drag race at our local track. I know the vette is faster, more HP, and lighter. My question is whats the secret to a good launch off the line? T/C on or off? RPM @ launch? RPM shift speeds? Tire pressure?? Again were both stock, both sticks, and I know he is faster, but I though if I can get a good launch, so I may not get spanked as bad. :yakyak:
