Default What fuel pressures are people with larger injectors running?

If you are running lower than stock fuel pressure, do you have any problems with hot starts?

Default Issues with hot starts are caused by it being too rich.

I am running the fuel rail at 40 lbs. With just the chip I had "hot start" issues, but once I leaned it out using the GIAC Mobile Tuner I was able to get it to start on the first crank just like it would during a cold start.

Default nDBW hot start fix:

push accelerator to the floor while starting (get off the pedal as soon as it catches).

think i originally heard it back in the a4.org days; some kind of "flood clear" technique, dunno if it works on the DBW. ...works like a champ on mine.

very rarely need to use it, but the apr stage 3 runs rich and if it is really f'n hot out (over 100F) and I try to start it shortly after shutting it off, it will need it.
