If you were going by the factory tach you probably didnt come anywhere near 7k. The higher you go the more innacurate the factory tach is. I found mine to be off almost 1500 compared to my monster tach. There is one year computer that has the limiter set at 7300. All others are set at 6250. The limiter pulls both spark and fuel, which can be disasterous under boost.
