I have a 05 350 with full fmf exhaust, pro design air intake with uni filter with lid removed, and gytr jet kit. It is jetted 165 main, 22.5 pilot. Idk if jetting is the issue but sometimes it will start cutting out, The dealership says it is rev limit due to short tires and small gearing, but i dont think the 350s even have a limiter. sometimes itll run fine through all gears, until i get to full throttle in 6th and will cut in and out. the parking break is removed and the dealership checked out the reverse wire problem. does anyone know what the problem could possibly be?
