Would it be a power valve problem? All jets are factory jets 88s on all four corners, and bleeds are factory 73 on idle and 36 on high speed.
If you have powervalves the 88's are way to big. That would be like running 98s without the powervalves. The powervalves add 8 to 10 jet sizes with the extra fuel they help deliver.
NOW IF you powervalves go down to at 78 to 80 jets and try it. I usually always block the powervalves but if your running alot on the street, you may want to try to keep them.
