There are MANY LS2 cars that dyno 340-350 on a regular basis, I've seen some in the mid-high 350s.
344 rwhp / 344 ft. lb torque on mine with only a KN intake.
Curious to hear that BMW helped design the suspension on the GTO. I will have to take a look into that. That would explain a lot. Definitely respect the BMW suspensions.
