Well I was seeing how much my 50 shot was going to help me so I went out on a country road and tested it out. The first time I spun through first so it didnt' work out very well. The second time I didn't engage it until the end of first. It feels a lot more powerful, well it did. I was in third and at about 8000 rpms I went to shift but missed and I just heard the engine rev up and hit the limiter. I eventually got it into 4th but it just started shaking. Then I tried the other gears and it shook to. I pulled it over and had it towed to my mechanic. He said I might have floated the valves and bent one....or possibly messed up the pistons and some other stuff. Anyone have any other ideas on what it might be??? I really need your guys help....please!
