I think my tune is pretty happy. Running 100% original GM maf table for the 4" truck maf sensor from zzp and 100% correct injector offsets and flow rate. WOT fueling is commanding a static 10.8 commanded afr. Fuel trims are within 5%. Only hacked table is the cylinder gain set to 1.2. Here are the results. Keep in mind this is running winter blend E85 (So actually e70) and a gas calibrated wideband.
