2011 GMC Yukon XL Denali AWD not as fast as I expected

I really like my new Denali AWD, but I am surprised that the 6.2L engine isn't as fast as my Sequoia which only has a 5.7L engine. Both have AWD, though the Sequoia is all manual. I think the Sequioa is rated at 380HP whereas the Denali is 403HP.

After driving the GMC for two weeks on vacation, my Sequioa feels jumpy.

Any suggestions? Is it normal?

Probably different gear ratios. I certainly don't have a power issue with the 6.2 in my denali.

Awd hurts acceleration performance. The drivetrain loss between bhp and whp is usually ~18%. Plus, you are in a 7000+ pound vehicle.

403bhp * (1-.18) = 330.46whp

My non-xl denali feels much faster than my step moms xl denali... The steering also feels much lighter in the XL denali. I think both are directly related to the longer wheel base. Just does not FEEL like you have as much power because the back end does not sag as much on acceleration...

I was never in the toyota, but I have driven the envoy denali, and jumpy is the only word I could think of... not powerful, or lots of torque...but it felt like a go cart kind of jumpy...

I was also considering a SprintBooster module to improve things.

Black Bear Tune IMO....

How much does the sequoia weigh?

Cai, black bear tune and lead foot and you should be good to go

How much does the sequoia weigh?

Curb = 6045lbs
Gross = 7300lbs

I don't know the difference between Curb and Gross.

Difference looks to be about 1300.....

j/k

BB Tune should help that out. My 6.2L doesn't feel slow at all.. I guess cause i'm in a SWB.

Iirc, curb weight is the vehicle as it sits, fully built, with no passengers or cargo. Gross is total weight vehicle can handle, including the vehicles curb weight, fully loaded not including a trailer. Don't take this as truth as I may be wrong here.

"s modified signal forces the throttle body to open 'more' than the stock signal at a given pedal position. In effect, the idle-to-full-throttle pedal travel is reduced. This makes your car 'feel' more powerful because a given pedal input produces greater throttle opening"

LOL! for 259$ I would advise just mashing the pedal further and getting a tune.

There's always a catch!!!

She only said you had to give her your credit card number. She didn't say anything about it being valid, activated, or even charging it.

Conner, you obviously are not married or dating! When a girl gets a hold of a CC, she knows what to do with it!
