What fuel pressure? with blower

[FlyBy763]

What fuel pressure do you guys that have blowers run?

I have 42# injectors...its currently at 36 with the vacuum line off...

I'd leave it at 40psi until you can get it on the dyno. There are just way too many factors to know the correct pressure without running an A/F ratio check.

Hey Jon

If you don't mind sharing info with the rest of us ... I got a few Q's.

I saw nothing in the sig about a tune soooooooooooo

I'd guess you're running those 42's with your maf caled to match em.
Hows the drivability with that setup and stock pcm?

How long have you been running this combo?

Do you have any idea about your af ratio at idle, mid range, and wot?

btw...I wouldn't have any idea about the fuel pressure thing...sorry.

I actually just got a chip for it this week...but I was running it for a bit without one. No dyno tune yet, but its in the works. I havent had any problems with it except at idle it would surge and sometimes stall, then naturally the hot starts would be almost impossible without holding down the gas. Other than that, I had no trouble as far as driveability was concerned. I just set the idle a little higher and it idled fine without stalling.

Thanks for the info Jon!

Looking forward to seeing your pull when you get it all sorted out.
