    O2 sensor issues with LT headers?

    I'm having this same issue with my StainlessWorks Headers, Both Downstreams are deleted, but my tuner said I have a lazy Bank2S1 sensor, so I'm getting two brand new ones Wednesday, but where is this fuse at? Mine was running fine and then it popped something and it changed it instantly into...

    Used prices and "the recall"

    Well let me share my two cents worth. See my Thumbnail? My Tahoe was hit head-on back in August. It killed the poor kid that hit me in a Hyundai Santa Fe, pretty big unit, I got busted up in my feet, right ankle and back in three places plus 8 ribs dislocated with 4 broken. I had over $50K into...

    2015+ push bar.. Setina or Westin. Other PPV items

    My Westin dealer said that my 2016 Tahoe LT 4x4 would lose the front collision warning system because of grill interference. Have any of you had to get that feature disabled in the computer? I really like that feature, it saved me one day in a bad downpour. JJ

Now, I'm looking for the best remotable HF radio for it. I have a Tarheel A200HP that I am...

    Mine had started doing this going down the highway, after stopping at places to shop, finally figured out, moisture had gotten inside the lead clamps where the copper wire going inside had become wet and then corroded. Whole CPU in truck would reset with me going down the roads here in AR where...

    2015 4wd Tahoe stalls loses all power

    Hello all! YES I DO! I just had weeks of this very same exact thing happen on my 2016 Tahoe Z71 LT and it left me stranded more than once in severe weather and with my grandkids but one day it just died completely. I found that even though the terminals are very tight and clean even with a...
