BayAreaRacing's LS2 GTO Dyno and Racing Footage (gto with launch control)
You guys might remember this car, well here is the never released dyno footage from it. 460whp n/a, never got a good run with the 175 shot but it did make over 600whp with it. Ill have to dig through and find some videos of it when its on the bottle.
Also one of the only GTO's you will see with 2-step launch control.
