When i bought my GTO, i knew to break it in before seeing what it could really do. i also thought that i would be basically getting close to the 400hp that is advertised for the engine. The other day i saw the dealer who sold me the car, and he had some interesting info which i don't know if i should believe. He said that the computer limits the hp to 350 until 7500 miles in order to break the engine in properly?!? I have never heard of anything like this so i tried to look up some info on it. One site mentioned how their new corvette was dynoing at 320 rwhp, other ones with 5000+ miles where bwtween 340 and 350. I guess i am asking if anyone else heard this, and if it is true, and why we were not informed if it is true? Thanks
