Need AFR. for my LT1
I thought air fuel meter maybe... but I hate assumptions.
The Aeromotive piece is prone to failure, TPIS used to make an adjustable one.
Otherwise convert to AN fittings and your choices are many.

If you had said AFPR we might have gotten it.[/QUOTE
Running a Golen 383 Forged stroker, custom grind cam,intake ported by LE w 30 lb injectors on stock AFPR and high flow fuel pump. Golen's paper work that came w motor says a AFPR is required for this build and I justed had a couple dyno pulls done and it was rich at idle and running out of fuel at WOT. Before anyone asks, the tune is by pcm4less.

Stock regulator should work just fine with a mediocre build like that, hell some guys use stock regulators at a LOT more power than your's will make.

What would cause motor to be too rich at idle and run out of fuel at WOT if not fuel pressure?
Lol... an afpr is not going to help.
It's either the tune, weak fuel pump, or not enough injector.
The rich at idle is 100% on the tuner. Assuming that info was gathered objectively, and not just "it smells rich".

Statements made in regards to richness at idle and running out of fuel at WOT were obtained from the shop where dyno pulls were done.

30lbs injector at 43.5psi at 80% duty with a BSFC of .5 (N/A Engines generally) only supports roughly 380bhp.
Yes you could up the PSI and it will act like a bigger injector because more pressure with each opening of the injector more fuel will flow out.
A 30lbs injector at 58psi will act like roughly like a 35lbs. Which is still to low for your horsepower.
EDIT:
Wait this is a engine dyno? 400bhp?
Because that makes a big difference.
