I am a noob first swap learning on the go so if I say something ignorant it is because I have never done this before.
I am running a 12212156.bin (from BoredTruckOwner) I customized with a licensed copy of TuneProRT flashed with LS Droid and a OBDXpro.
1. The truck runs rough at cold start with the 12212156 tune

2. I keep getting lean bank 2 (red) & lean bank 1 (yellow) not sure what is going on but I am thinking it is the 12212156 tune

When I run the original LM7 9373372 tune it lifter rattles at start but runs smooth
I get no lean codes (I do get O2 bank 1 sensor 2)
Since 12212156 is written for a stock 2002 LM7 and this is a stock 1999 LM7, Maybe there are differences in the fuel systems?
