I have done a lot of reading and watching videos about MAF and VE tuning and they all seem to say get a wideband sensor, turn off DFCO, PE, DOD, disable MAF to tune VE and vise versa, etc. That all makes sense and I will definitely do for WOT tuning. But for right now, I am only interested in part throttle cruise tuning and light acceleration. Please correct me if I am wrong, that is why I am asking, but I see no reason the stock narrowband sensors and LTFT could not be used to tune cruise and light acceleration without disabling DFCO and PE. DOD is of course disabled.
The only thing I am unsure of is tuning MAF and VE at the same time, without disabling one to tune the other. I am not sure how and when the two work and if that is even possible. My LTFTs all seem to be between -8 to -12, so it seems obvious it could use some adjusting. LTFTs have never been reset or disabled, at least not in the past 15,000 miles.
Vehicle is 2017 Silverado 1500 5.3L-L83 6L80E.
