Fuel trims should lock in at zero. What are the LTFT's at idle and cruise? Do you still have your stock PCM, or did you send it back to ZZP?

Idle LT is -0.7 and cruise LT is -2.3 if I remember correctly, I would need to look again though. But yes I sent the stock unit to ZZP, wasn't thinking I would have a problem you know?
I liked my tune done by Overkill. Wires won't make any difference, except that they look cool. a bigger throttle body with a bigger mass air flow sensor, like the combination I have for sale in the classifieds, will increase the volumetric efficiency of the engine resulting in more power.
My mistake, cruising LT is 0.0-0.7
So an in-car tune it is to kill this KR? Any other things you can think of?
Jesus i have a lot to learn lmao it usually doesn't snap to 0.0 but something like 1.5 or so during these instances
It snaps to 1.5 at WOT, no fluctuations.
Watch the wideband is what I always do.
To me it does not matter if they are within 3-5% of zero and the wideband says I'm good on fuel. No way that that small percentage is going to matter really.
The stock maf calibration on my 2012 silverado with stock airbox is within 2% of zero all the time and it doesnt change a thing.
I don't have a wideband however, can I bad wire cause knock?
