fuel problem running very lean need help

[sheezy'sES]

i've got an 03 lancer which i turboed recently. i've had more problems with this thing and now i found out at the dyno the other day, i'm not getting near enough fuel and just wanted to ask some people what my problem is. i'm running 5lbs of boost on a turbo specialties t25 intercooled turbo kit with a walboro 255 fuel pump. i only made 133 hp and the air fuel was nearly 15, so lean i'm in trouble...i'm not getting any fuel to make any power. i could only make one pull, the guy was scared to run it again being so lean. the fuel pressure regulator on the car is not adjustable, but was supposed to be good for 8-10 lbs. so i'm confused as to why i'm not getting any more fuel than i am. i'm going to replace the injectors now and got a quote from roadrace for $450 for the 360cc injectors they have for their turbo kit, but is there a cheaper way out than this?? i just need a little help from people who've already done this. any advice would be helpful. thanks.

Well, for one this is the Ralliart forum so u posted in the wrong place as you have a ES. I not very familier with the ES's engine, However if the stock injectors for your car a low impedance injectors you may very well be able to use DSM injectors from 1g and 2g eclipse's and talons with the 4g63t engine. The Stock injectors for those cars are 450cc and would work perfectly for you.
