nah...Z06 are underrated and make 460-470rwhp which puts you beyond 505hp. I make close to 500 crank horsepower (428rwhp) and ran 11.7 @ 122 on street tires. Manual non-z51/gs.

Made a pass the other night. 05 ls2 all stock with 100 shot on street tires. First time running the car. Launched and 2k rpm and still had traction issues. I spun 1st and through 2nd. I had a terrible time of 12.954 and a trap speed of 117mph. Can't wait to run the car again and learn to launch the car better. Tire psi was at 25lbs also.

I think you need a different dyno and tuner.

It may feel great as a passenger, but if he really has that much HP (500crank/428wheel), he should be running quicker than 11.7 @122. Either the dyno number is inflated or the tune is holding him back. With only headers and a tune, I'd highly suspect the dyno # is off. Admittedly, it's not easy to launch on street tires, so 11.7 with around 400-410 whp sounds closer to reality.
The '06 Z06 was the first car to have the HP rating done under the new standardized method that required certified conditions. http://www.sae.org/certifiedpower/details.htm
The 505 HP is real and most Z's are in the 440 whp range. The Z06 fast list for bone stock w/OEM tires has plenty of cars 11.7 and quicker.
