I start tuning the 6.2 denali with a wideband since i took off the catalytic's on my exhaust. Well i put my file to open loop and strat driving normal, Air fuel was on the high 14's so i made some changes. I did a WOT to see how they where they were way off they where at high 14's made some changes lower it to on the low 13's, but i was drivong normal and the MAF read up to 6900 hz and i had made some changes at 6900 hz at WOT so now when i drive normal it's reading a few HZ where Im at WOT and its throwing off my AIR FUEL at normal driving.
Can some one help me out, What im doing wrong here.
