here's another weird thing to add to the mix...... there are times that my vehicle feels like a rocket and other times it feels like a slug (not while towing). I'm totally lost with all this. Would it help to swap my gears from 3.42 to a 4.10 or 3.73?

Ran some logs on the way home. Obviously the load is a little lighter on the return trip with less food/drinks.... I believe my total tow weight with camper loaded is around 5k lbs. I dont know if this will shed any light on the situation or not....

Ran all low octane out. Refueled with 93 octane from a different Exxon. Ran through half the tank and flashed stock tune. Ran for about 100 miles. Flashed custom tune and refueled from same filling station. Towed camper on Thursday. I got 6 miles per gallon. No performance increase on top of the ...

Lew,

I'm telling you man, other than the hard shift when I 'get on it', nothing really feels any different. I'm using Exxon 93 octane. This is why I was asking if my initial logs looked ok. I'm not trying to bust balls or troll anyone. I'm dumbfounded as to how all the real gear heads around here ...

After swapping tuners, updating and getting proper tunes loaded, doing some logs, and 1 custom tune, my feelings have not changed. $400 tuner, $100 custom tune (which was miraculously perfected on the first attempt) and a years' worth of high octane gas, my vehicle doesn't feel any different. I wish ...

Thanks Michael

Sounds like you were having a day like me......

Can we get a fix for this? Please?

Ok, can someone tell me what tune I have on my truck at this point and how do we go about getting the TCM straightened out?

Ok, I did that and it said it installed something lol. So now, I'm on factory tune?

I tried to restore factory tune. It says there isn't a restore tune to load. Here's my .xml file. Can you tell by this, what tune I'm running? If it isn't stock tune, please tell me how to I can recovery mu stock tune.

Also, I loaded that file and let the tuner recal the current tune on the ...

Thanks Mike. I haven't tried it on the vehicle yet but, it now says it's up-to-date.

Ive attached all of the files I can find on the Intune drive.

Hey guys, I received a replacement Intune and I'm getting these error messages. Can anyone help a brohter out?

Thanks!

I was told that those codes are proprietary to GM dealers. Typically it ends up being the seat belt buckle on the front passenger side. That's what happened to my 07 Suburban on the day I was taking it in for a trade-in estimate lol.

thank you, sir! I hope we can get this baby going.
