    Not a fluke. Filled up the tank again and I’m seeing 382 miles for the range.

    Better drifting, worse mpg

    AT psi

    Pics loaded sideways lol 36psi I was getting 302 miles a tank since October of last year. Bumped it up to 42psi a week ago and ran almost an entire tank of gas before refilling. Now I’m seeing the normal range of 360-380 per tank

    Tire pressure seems to be the culprit here. 36psi vs 42psi. I’m seeing better fuel economy with 42.

    AT psi

    Thanks for the info! I had a feeling they were running low. I’ll bump them up some. The pic was taken in late Jan. this year. Took them out on an old logging road. We found a place to go shooting and played a bit in the mud. Not sure about Yankees. I grew up in Texas, and let me tell you...

    Switched from factory 16 to a BFGoodrich All Terrain KO2 LT265/70R17 6 ply. What should my PSI be set at for good MPG? Daily commute is 25 miles highway stop and go driving.

    4L60E Parts

    Thanks Mike! Not going to rebuild it. Looks like the burning smell was a burnt 30amp fuse for the trailer brake (stud2). I appreciate the guidance. I need to stop jumping to conclusions I guess but I’m just so frustrated with the sudden decrease in mpg when I haven’t changed driving habits and...

    With all that said, I was curious about what parts I should look for. Thanks for the advice.

    Interesting. What does the corvette servo in our transmission exactly. How does it change it? I’ve read (here) about people using them, but never learned how they change the trans.

    4L60E Parts

    Started noticing fuel economy decrease last October - went from 360 miles a tank to 300ish. Shop has checked fuel trims, etc, no issues everything looks normal. Ran seafoam through the engine and gas tank and switched to ethanol free gas (5 tanks now). That made a slight difference (increase) in...

    170k on factory plugs

    Truck didn’t come with owner’s manual and my research is turning up mixed part numbers for new plugs. Can someone confirm the AC Delco spark plug number for an 05 Tahoe LT 5.3? So far I have 41-962 gapped at .040 Just want to make sure that’s correct Thanks

    Has my truck been lowered?

    Turns out it was a Mcgaughys 2/3" lowering kit (33048). Changed everything out this weekend.

    Has my truck been lowered?

    Bilstein 5100's showed up on my doorstep today, along with a set of Moog 81069 springs. I have coil spacers and new keys that I was planning to use on my Yukon...but I can use them here too. I like how the Tahoe sits now but I need to be able to tow, and I cannot tow what I need to tow with a...
