So heres my issue. 1st 2nd 3rd gears drives great. Alittle bogging/hesistation in 4th and alot in 5th. My tach is a bit messed up. But by listening to the car its only in lower rpms in 5th gear. punching it in 4th stays at a certain rpm but doesnt bounce. also i can pressed down all the way on the gas pedal in 5th gear and it just keeps bogging till i let off then press it again then its fine for alittle bit but as it goes alittle more up in rpms it boggs. I was thinking fuel pump? Its not producing enough fuel (pressure) under WOT? Any other suggestions? Btw this is freeway driving. In city/town drives great. Also speedo isnt working. And im using an auto ecu.
