my cousin has a automatic plymouth neon and we just put a tach in there(didnt come with a stock one). while driving it shifts normally(at 2300-3000 rpm), but when he floors it, it still shifts around 3000-4000k rpms. are there any ecu's thatll allow it to shift higher? once it goes past 3500rpm you can feel it pull but all of a sudden it shifts.
