Near stock LS2 371rwhp/389rwtq Got my 05 GTO 4L65E dynoed and was surprised to see the numbers it put down. Mods in sig.
This was a dyno dynamics dyno. Dyno operator thought it might have a cheater cam in it but the car peaks at 5600-5800rpm for horsepower and falls off after 6000rpm. It did have 26 degrees of timing at WOT which indicates it might have a tune but the A/F was in the low 12's in the upper rpm and I can still feel the torque management is there.
