I am tuning a 2000 4.3 turbo with marine intake and stock bottom end. I am using the 411 PCM. My problem is, when i go and start the truck cold it seems to run good, the AFR error table is in check. I can drive and log, all is well. Once I park, sit and idle, turn off the truck and immediately start it back up, now everything is lean. I'm lost. I will post the tune and the 2) logs 1) good 1) lean.
Also, Once I think I have a good tune, where should i post my tune to get some experienced eyes on it. I'm uncertain on a few things.
