So just tune the Maf frequency Hz accordingly to bring the fuel back in? When tuning the trims do I watch LTFTs or STFTs? Or both?
if you're running a maf-only tune then yes just tune the maf frequency.

if your running a maf and ve table tune then you need to tune both of those individually

remember to have ltft and stft disabled and just use the calculated ben from the wideband
