Yes, I am talking about the main jet size in there I put a 148. I ride below 3000 ft most of the time the odd times I will climb and ride up there around 3000 - 4000 ft. I ran good the first few times I went out up top with the main jet set at 137.5. down low the sled ran like crap which I expected. I think the carbs are out of sync. I adjusted the air fuel mixture screws to 2 turn out as recommened by the Aaen tech support and installed 147.5 main jets as I have been told that these pipes like to run a little richer than the P.S.I and other aftermarket pipes.
