    Hopfully a quick answer to a problem I'm having?

    07'tbss 6.0 my mpg are coming back after a couple problems and sensors failed.
    Filter got dirtier than I thought, but I had 18 mpg and lost it.
    It coming back and the afr is good driving but when I come to a stop 3-5 seconds later the afr go's 17-20!!!! And misses alittle??? I'm getting 14.7-15.5 on the gas.
    I tuned the v/e correction factor and it's great! The table starts at 65kpa and nothing done low? What table should I try first.

    160°thermo
    4" cold air kit no lid
    Ram air hood functional
    Pacesetter headers and y-pipe kit no cats!
    Magnaflo 16-17" turbo muff and tail pipe no resonator
    Tr6 plugs
    That's the only issue is the afr at idle and it's killing my mpg. Runs great other wise. 13's easy!
    MAF calib low freq:table is .127.151.180.215.256....

    You really should post the tune for more help.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
