Hello. Buddies car has been running for about a month. LS1 with turbo . We have been getting closer with tune
thinking we are close enough to bring to a dyno. All of a sudden, this problem showed up. It justs shuts off when
it starts to build boost. WE used to rev to 6000 and 8lbs boost and Afr was rich but safe . Now look at the log. Frame 475 then 476. inj duty-pulse fall off. Map drops. Throttle pos the same until he lifts because it stumbles then dies. Fuel pressure
falls in less then a sec. Argh. Checked all fuel pump wiring. Not sure what happens first. Car dies , pump shuts off or pump
shuts off then car dies? Really hard on mtr trying to figure this out. Log and Cfg. Please look and any Ideas for us.
