I had 4 passes at the local drag strip this friday. . First one was all good. Last 3 passes, launching from 2nd once it gets around 4000rpm, lpfp crashes to 20ish psi, followed by rail crash and injectors cut off code. I was at 1/4 tank. Ive had around 40 passes this year at 1/4 tank or lower with no issues. Walbro 525 bucketed setup. Driving home did a few logs without issues. 2nd 3rd and 4th gear and gas being at 1/8 tank. Even tried a launch on the street and no issue, lpfp stays above 60psi, but it obviously doesnt hook like on the track so the G forces are much smaller. Did anyone experience anything like it ?
