My 06 LS2 with about the same mods as yours showed max power 370.5hp at 5800 rpm and max torque 374.9 ft-lbs at 4359 rpms.

Yes. I was very disappointed!!

Every dyno is different tho, some read lower numbers than others and even the same dyno will read different numbers on different days. I know when I had my C5Z dyno’d with long tubes it was a low number but it was because it wasn’t on a dyno jet, which typically has the higher numbers… the car ran great tho.
