Accel Gen7 tuning issues

[thedugan]

While I try to figure out who to bring the car to for help with tuning issues looking to still figure it out if I can.



Been messing with it on and off for 3 months and not making much progress

Running a SBC with superram intake, gen7, wideband, 55pound injectors.

Car starts fine and runs but has very low vacuum. 8-10 pounds. I have checked for vac leaks and cannot find any.

Fuel pressure at the rail shows 45 pounds, which is what I have the ECm programmed for. Running a walbro pump in a rock valley efi tank, with a single line to the front thru an aeromotive bypass regulator referenced to vacuum. The one issue I might see is I dead headed the rails.

AFR is fine when it starts up but once it warms up it goes full lean. I am not sure where else to look to fix this. No exhaust leaks ahead of the sensor to throw it off.

Any ideas guys. And anybody know a good tuner in Northern NJ or eastern PA
