I havent been driving 5th gear up and down any hills around here so i couldnt say for sure. But this problem is basically felt on every gear in the upper rpm's, i just dont feel it as much because im usually shifting at that point, and when im in 5th i feel it plenty at around 75 trying to pass a car and i just cant get around them because she's choking out and sputtering. I got pilots being sent to me from nightrider and dog_33 from this site, and when i get them in I'll be able to experiment a bit more and finally get this problem sorted out.

Big thanks to both those guys

Tom
