holy shit avalanche must be heavy as fuck. MY 5.3 silverado and 5.3 yukon xl are much quicker.

[wjcollier07]

yeah, curb is supposedly 57XX, but whenever I drive over a scale, it shows over 3 tons, empty.

Your silverado is probably 1000 lbs lighter depending on configuration, but your yukon xl should be identical, since its on an identical platform. Care to take a video and prove this claim?

[Rlnthndr]

Im not bashing, but im just amzed at how slow it is, I though the weight was almost identical to a crew cab silverado. Didnt realise it was heavier. But i Have a video of both uploading.

Oh, no, I know its slow. But nothing's wrong. I had it on a ScanGauge II last weekend and did a few runs, and according to that device, it nearly always hit between 293 and 298 hp on every WOT run, a few times it felt a bit more powerful, and the device read out a maximum of 238 hp. Its definitely held back a bit with torque management, but I'm not real fond of the idea of unleashing it on the little 4L60E that GM decided to use for this vehicle.

Do you really average 17/18 MPG?

[wjcollier07]

cont from first comment: I use only the best of everything in every respect. Both differentials are running Mobil1 gear oil, transmission has dexron 6, engine has Amsoil SSO 0W-30, air filter is a purolator pureone...all up to date. My only guess is that GM's claim of 100,000 mile ignition system tuneups is complete bullshit. I'll be doing a tuneup in the next couple weeks with MSD wires and Delco Iridium plugs. We shall see if my mileage comes back.

[guitarsnowmobiler]

[abram7117]

seems like that 5.3 struggles a little to get that truck going. then again thats a massive heavy vehicle too.
