Well, here's the story. Everyonce in a while when it's cold I can hit the rev limiter in 1st gear and it like bounces off the rev limiter before it shifts. Since I have installed my water injection I can do this everytime if I keep my foot on the floor and it doesn't just do it once it sounds like it does it twice before it shifts. Scared me the first time, almost like a Ricer sound hitting the limiter. Any help suggestions, answers to why this does this?
