Hi folks, just put a Z06 air lid on and took it for a run (roads still dry here believe it or not) It seemed to be quite an improvement. Not sure if it was just my imagination or not. Anybody have an idea if it actually adds any horsepower or not if thats the only change? How long does it take the computor to adjust as well? I had it out for about 50 miles. Thanks
