A stock G8 GT makes around 315 RWHP.
All but one of the GXP's we've done have been manual transmissions and the only auto was baselined with less than 50 miles and then we installed a Magnacharger, Rotofab, Corsa Exhast, and tuned it. I feel the numbers were very low due to the mileage. It made 330 RWHP stock.
Our GXP manual was baselined with 20 miles, then again at 1,000 without any mods and it picked up 20 RWHP.
Once they get some miles, they all seem to make around the same baseline numbers.
