nice to see another megasquirter
Fuel pressure on my system is about 30-40 lbs without any significant change with boost although I can't log this yet. I actually had purchased a BEGI RRFPR to use when I did my turbo conversion but I decided it would be simpler and more accurate to go with larger injectors since I had complete control over fueling and ignition with the MS. The main trade-off is idle quality with the larger injectors. I am waiting for the MS3x boards to be released to convert to full sequential injection and direct ignition control with LS2's. From what I have read, this seems to be the ticket to get big injectors to idle better.
