The ls4 is underrated imo at least torque wise. I owned an 06 monte ss for a few years and that thing felt torquier (not sure if that's a word?) Than my current 300whp 350whp+ l32 gp. With only a cat back that thing was a beast down low. I know the gearing is a little different and there are a few other differences between that and my comp g, but my point is don't underestimate an ls4.

Also, if you're asking how to launch I assume you can't drive for crap, so if he can launch, he's gonna win.
