I believe I have a couple issues....... Car goes lean under even light boost condition, have checked for air leaks and have no issues. Has a new deatschwerks dw300 pump, hotwire kit and billet adjustable regulator fuel pressure goes up on a one to one scale, base pressure is set at 45 psi. I have noticed while driving and starting to roll into the throttle that the AF numbers never go above 45-50 it is my understanding that I should double that number with the translator and LT1 MAF. Also noticed that the car idles a little rough. O2 sensor readings tend to fluctuate very slowly, planning on replace O2 sensor just for good measure. Just trying to avoid replacing a bunch of parts. Also as I said in the title shows no timing being pulled on scan master. Have n innovate motorsports wideband and gauge on the car when first lightly accelerating it will go 12.5 or so to one but as soon as boost hits goes to 13-14 range.Have a scan master and can post all numbers just looking for some help here. I can work wonders on OBD2 cars with EFI Live but this old school stuff baffles me a little. Thanks in advance for any assistance.......
