my car with 110,000 miles on it made 320 rwhp and 332 rwtq with only a lid and neutered catback. stock tune, stock ls1 intake, etc, etc. i think that's pretty healthy for a car with that many hard miles and so few mods. and it wasn't just a giving dyno that day either, i ran 12.8 @ 108 the night before on shitty kumho street radials cutting a 1.8x 60 ft. and the car hooks VERY well on the street. i dunno if that would be considered a freak, but it has put quite a few cars in their place that it shouldn't have (pulled on cam/bolt on cars off the line and held them off for 1/8 mile)
