Default quick question regarding histograms in HPT (dialing in MAF)

Hello, its actually a quick question. Im trying to dial in my MAF and im checking out my data from the log, and i was just curious, are you supposed to have negative values for your MAF - AFR error histogram?

i can provide a scan, tune if you'd like..

thanks in advance!

That is correct. Do you have a wideband installed?
