5 years later and I don't think I'll ever get tired of this truck. 6" bds coilovers fuel vector 18x9 and toyo rts 35x12.5

Yes there have been other reports of range doing this. You don't need to worry. My amp steps are plugged into the obd and onstar reads everything fine fwiw Sent from my SM-N986U using Tapatalk

Check battery cables and if those are good check the ground in the top of the dash Sent from my SM-N986U using Tapatalk

It would be awesome if we could see your valves! Sent from my SM-N986U using Tapatalk

Have you done any valve cleaning in your 100k? Sent from my SM-N986U using Tapatalk

Man, you really must baby that thing. Nice work. Sent from my SM-N986U using Tapatalk

Good stuff! Thanks for posting. People need to keep in mind that forums are places people usually seek out to find answers to problems which would make it seem like these trucks are garbage when browsing GM-T.com. Same goes with any other vehicle forum. Sent from my SM-N986U using Tapatalk

My entire tank got replaced under warranty due to this issue. Sent from my SM-N986U using Tapatalk

Got a list? Just curious. I've had a few as well Sent from my SM-N986U using Tapatalk

Honestly it sounds about right. Try slowing down and you could do a lot better. I bet you could get 11 at 60 Sent from my SM-N986U using Tapatalk
