I think my fuel pump is taking a dump on me. heres the run down. Armageddon TT kit on 16lbs. Has lt4 hpfp and injectors and meth kit also. Stock motor and trans. Truck was running great it ran a couple 10.80's at 126 mph. Went to the track last night and ran horrible, started surging really bad.. Would like you guys to check out my log, it seems that the fuel pressure isn't where it should be..
Yeah both low and high fuel pressure tank and you picked up a misfire. A low side fuel pump and one of my plug and play port injection kits will solve your fueling issues forever. It is Russian roulette relying on meth injection for fueling on big power combos.
It is good practice to log your injector pulsewidth too, ignition timing dropped real low, that is the ECM attempting to help the problem of low fuel pressure.
