I have a 25 Denali 6.2. When I go to pass another vehicle and jump on the gas it goes like a bat out of hell. When I back off the throttle it seems to want to keep the RPMs up for a bit. Does this sound like a normal occurance for these truvks.

I hate to be way off topic here but is anyone else unable to sign into the forum using Google Chrome. I keep getting this error message.

Gladly I'm able to log in under Microsoft Edge as a second resort but Chrome is my default and preference browser.

I retired from the Tonanwanda Engine plant. I worked in the crankshaft dept. The quality checks we made were held to very strict tolerences. I think the cranks produced at Tonawanda will be great. I'll have living proof just picked up a 25 Sierra 1500 Denali 6.2 Tuesday. Runs great.

Traded my 23 Denali 5.3 for the 25 Denali 6.2.

Bikerjon. you are absolutely right I test drove a 25 Denali 6.2 yesterday. Was so impressed I'm picking it up in about an hour. I guess the old guy in me told get the Denali and not the AT4. I like comfort and don't need the offroad capablities

My only concern is my driving is mostly short city drives. I'm sure longer highway drives would be better for the LZO. The fuel cost in my area, Diesel and premium are pretty close in price. Def just adds more cost to the LZO. My 23 Denali 5.3 is a great vehicle. I should just keep it but I get bored very easily with my vehicles. I have an oil change due in a couple weeks with too many decisions to make with these engines. This wouldn't be the first time I left for an oil change only to go back to the dealer with my title and a check, then drove home later with a new truck, Decisions decisions.

Pretty sad GM can't get their act together. I might just bite the bullet give up a couple more MPG and get a 2500 AT4 with a 6.6 gasser

I'm sitting on the fence looking at 25 AT4 but can't decide on the 6.2 or the babymax. I hear a lot of emission issues with the 3.0. Not liking the reputation of the 6.2's over the past couple years. I have a 23 Denali 5.3 right now, I'd rather get an AT4 this time but no 5.3 offered.

I hope they roll it out to the 23's That dismal BOSE system is a real dissapointment.

Get the same thing with my23 Denali 5.3 10 spd. Drive mine in in sport mode, gets the rpms up when it shifts Does your 2.7 I don't notice it. Drive in L9 shifts smooth as silk. Does your 2.7 have DFM? Mine does and I was thinking its the culprit.

Its very weak. The bass on my 20 SLT with Bose system completely blows away the Bose system in my 23 Denali

My 23 Denali 5.3 has the same shudder around the same speed. I'm thinking it has more to do with the DFM than the transmission. Try running it in L9 from the start. Drive it the same as you would in drive. No cylinder deactivation and no shudder. These trucks shouldn't deactivate cylinders at that low of a speed.

It came standard on my 23 Denali signed into it but haven't used it yet.

Second winter on my 23 Denali not problems. Snowy and salty in WNY

My 23 Denali has been hit and miss with my Pixel 7 pro. I got used to cursing at it and adjust it couple times then it seems to locks in.
