I would think the 42 lb injectors are good for 10 lbs of boost.
They are with the 255. I think my problem was because of my 60lb's. Even at 6LBS with the stock pump I went lean like 15 at 3/4 throttle.

42/44 lb injectors is right at the limit at 10 psi. this of course depends on were you live... At sea level you better have meth for anything over 10 psi.... to be safe

With meth, two nozzles and 44, I can hit 15 psi in reno, at sac I can only hit about 13.5, keep in mind the other MAJOR fact is RPM, I shift my $hit at low RPM levels....

Seems a little rich to me. I like to target 11.5 or so while in boost.

Allen did my tune. I am sure he kept it rich to make sure things stayed together...I would say it is rich also. Maybe just by getting that to 11.5 will pick up enough power so I wouldn't need to go to 10 psi.
