Finally got my truck to the track tonight, had decent results. My best pass was a 15.05 @ 93.5 MPH. I ran the truck in 2WD and my 60' time was 2.357. Was slightly disappointed I didn't break into the 14s. Not bad for a loaded LTZ crewcab though.

Is that bone stock? Did you have traction issues? Is that with the 3.42 or 3.73 rear end?

 

Still not bad for a big truck though!

thats pretty good. i would kind think that the 6.2 would be faster though... my 2001 silverado 5.3 runs 1/4 in 15.8

Yeah it is bone stock down to the paper filter. I have the 3.42 rear axle. The 6.2 is really held back by the ridiculous factory tune, I'm sure I could gain at least 5 tenths with a real tune.

I'm still undecided on a tune. I don't wanna blow away my warranty.

If you're looking to tune definately check out Black Bear Performance. They do great work and have a device called and Autocal which allows you to switch between up to 5 tunes for dealer work, towing, etc.

Theres a tuner in my area that does alot of GM stuff and people are happy with the work. I would prefer an in-person tune for TCM calibration.

The DA was about 1300ft. I think track prep was the issue, we had alot of rain here lately and the track was really green. A 2.357 60' time is pretty lousy.

Did you only get 1 run?

 

I agree 2.3 sixty foot sux but big v-8 in pickup truck with stock tires and no load in the bed you wont be able to get much better.. I am curious what you woulda go in 4wd. Probably 1.8.. theres your 5 tenths right there. Im sure the time that woulda been made up at the holeshot would more than make up for any power losses on the big end of the track in 4wd.

 

 

What about 4wd launch then click down into 2wd? I have never tried doin something like that WOT.

i assume its the same on the GMT900's, but when you floor it off the line in 4, your can safley switch back to 2 at any speed. thats how my buddy with his 05 dmax does it and i have done it in all of my trucks

      2027 GMC Sierra: Official Discussion

      I was the GM of a Lincoln Mercury dealership back in the 80's. The service lot was always full with "broken" ones. Plenty of transmissions, power windows and a/c repairs. The only one I'd consider owning would be the Marauder at this point and it certainly wouldn't be a daily driver.  My 2025 GMC Sierra 1500 Denali Ultimate is my "Lincoln Town Car" in my retirement. I want all the "stuff". Big infotainment screens, one touch power windows, Supercruise (I won't buy another vehicle without it), hands free pretty much everything. I'm going to swap my current truck for a 2027 Yukon Denali Ultimate so I can have the air suspension and surround vision recording along with all the other "stuff".

      The Denali Ultimate's grille is tinted, but the "regular' Denali has a bright chrome grille like the current models.

      Because that is IDIOTIC, much like this question. They've already been forced to do it by past administrations - why would you roll that back when it's a GOOD thing?  WHO IS ARGUING FOR LOWER MILEAGE???? 😂  NOBODY IS!!   I'm certainly not! What I want is RELIABLE vehicles again that are worth the price paid!    I don't get your logic here ...   In 2003 I paid $2,200 for our '86 Grand Marquis. It's STILL running and I've never been inside the engine, aside for the timing cover since it was leaking, so I threw a new timing set in since that makes sense. Transmission is ORIGINAL. Electric pump in the gas tank is ORIGINAL. Rear end is ORIGINAL. I'd have to hit my head REAL hard to want to pay $60k or more for a car that still can't come close to the comfort, seating and storage space, or reliability of this one. Nothing is even in the ball park! Hundreds of thousands of brands and models have been built and sent to the crusher while this one keeps on going!   https://postimg.cc/Z9XRrCSg   I've got a whole fleet of cars, motorcycles, and a truck close to this age for summer and winter. No one could pay me enough to buy anything built this century. I have zero use for any it.

      Since I'm the one who has to fix them when they break, I'll take vehicles over 30 years old all day, EVERY day, over ANY modern crap. Have you attempted any repairs on anything built after 2006? It's a friggin nightmare, and gets worse the newer the model year.    If I had the will or desire, I can make any car of any age outside of a Model T (I don't have THAT much will ...) just as powerful, comfortable, and have all the tech the new stuff does, and get pretty close in mileage, too. I prefer SIMPLICITY. The less the vehicle has, the less to fix WHEN it breaks, not IF.   I'm glad you snot-nosed punks don't like them. More for us, plus that keeps the prices from climbing more than they already have.👍
