had a simular problem. When I got on it it would start to stumble around redline then kind of fall back in rpms a little. I thought My trans was the problem, not shifting out then loading up on fuel and falling off. Notta I tried to get it out with a tune only to find it still happened. Then I replaced my injectors and bingo. Now it runs great.
