So all last year I got all my part throttle and some wot tuning done but when summer hit the tune was way off even though it was the same temp. Well now my MAF table in scanning is always showing positive numbers so I copy paste onto tune by .5% and then my LTFT start going negative. I thought I was trying to get my LTFT to 0 and I was doing this by MAF tuning but it seems to not be working. Is my wb going on me or what. I'm also getting huge kr but afr is good but not my LTFT.
