dead pedal 3.hpl
latest fuel shutoff tune.hpt
first hole shot it runs fine. Hit the rev limiter, shift, hit the limiter in second, grab third all is good. Come to a stop and do it again this time usually around 6000 rpm its like the fuel shuts off. Scanner shows injector duty cycle drops off before anything else. Mechanical fuel pressure gauge shows no change when this happens. Motor is a flex fuel 5.3 with mild head work, 4.8 pistons and a cam motions little chopper cam, headers and 2800 stall. this is in a rock buggy with a turbo 350 trans if that helps. Pretty new to tuning so im sure its something simple. The original cam only motor ran flawless. Everything else the is same, sensors, injectors, etc, except for my ve and idle tuning. Any help would be great.
