on my TBSS dashhawk 0-60 3.9 when i had a yank 3600 stall in there, 4.6 on the stock converter.. is that how you were measuring the 0-60 times you have there? have you run it down the 1/4 yet?
Anyone Got a 6.2L

I know where Classic is at, the huge place right around DFW.
I would say $56k is a good price, but to high for a Tahoe IMO.
I would say just get a Denali at this point.
And when I said sluggish, I meant the 6.2L Tahoes do have more power when your behind the steering when compared to the 5.3L, but for some reason they don't feel as good as the 6.2L in the Esky and Denalis, just what I heard!
Just as a little bit of a confirming opinion on sluggishness (depends on your reference point):
Earlier in 2009 I drove several 2007-2009 Escalades (probably about 6 of them) - 1 for an extended 2-day / 200 mile test drive. I was unimpressed in general, even with the ones that were broken in (used).
See my signature for other cars I currently own, which are somewhat valid to this storyline re: sluggishness. I also had a 2007 TBSS 3SS 2WD for a year and put 20k miles on it before I decided it was too small.
In September, I was going after a 2009 6.2L 4x4 LTZ Tahoe at BELOW employee pricing. But, in the end, my alternate deal on the 6-mile, just delivered 5.3L was too good to pass up.
$3600 more for an extra 70hp (+2-3mpg worse) just wasn't a priority of mine since I have those other cars to "go fast". The 6.2L is only a $1000 option, but dealers wouldn't come off as much because they are rare.

I haven't run it in the 1/4 yet but I would love to find out what it can do. I have used the DashHawk, G-Tech, and Dynolicious and they all gave similar results. I know these times aren't 100% accurate but they're in the ballpark.
Those are impressive numbers on your TBSS. Do you remember what it ran stock?

TO BE fair too the only real 6.2 experience I have with is with my old sierra denali (no longer own it) it was an 08 and I put about 5000 miles on it. Was quick as hell. But the truck is what 4900 pounds and the escalade and tahoe are 5800? But 403 hp is still quite alot. Its just two less than a c5 z06
The MPG difference is negligible. In fact post-tune I get 19-20 HWY if I keep it to 70 MPH.

at the track ran 13.49 @102.xx with 2.00 60' shit load of 13.5's worst hot summer days at EnglishTown running 13.8's or so never less than 100mph most over 102.
Actually the Sierra denali and Tahoe have same curb weight 5580 or so. The Tahoes with the 6.2 are just as fast as your Denali was, so your impression of the truck being as quick as hell would be the same for the Tahoe with the 6.2. Don't let anyone fool you the 6.2's in anyone of these 90's is quick as hell for an SUV. Only thing on par are the Toyota Sequoia/Tundra..

If the Escalade uses the same 6.2, then I don't think it's worth it. It seems like driving my mom's takes more force, but I guess it all adds up since it's a bigger engine and hers is an ESV so the truck is longer. Still, I'd prefer my 5.3, though hers sounds better stock.

i have had a 6.2L for over a year and LOVE it. i have to admit that i did have a little bit of a rough idle (but it only happened every once in a while). But i almost NEVER noticed it. once i got a tune, Justin with Blackbear fixed the idle and i havent had a problem since.
trust me.....get a 6.2L. with a tune i almost feel like i have too much power for a big SUV

True, the trucks do seem faster to me.
I had a 2004 Silverado VHO (2wd SS precursor test model) - 6.0L......it was a lot faster than the 6.2L Escalades I have driven.
But, when the 2007 VMAX crew cabs came out I went to test one and thought it was slower than my VHO.
I think it's just the detuning GM does these days to keep up their end of the 100k powertrain warranty.

Yeah, I'm sure it's not a ton.....I recently saw over 21mpg going 78mph (I prefer to go faster than 70) on a 400 mile trip. It's not way different, but it's a couple mpg. I have owned: 2004 Silverado VHO 6.0L, 2007 TBSS 6.0L, Currently own 2007 C6 Vette, 2009 G8 GT (both 6.0Ls). I recently got rid of a 5.3L 4x4 Avalanche. It is way heavier and got at least 2mpg combined cty/hwy more than the VHO (L76). The TBSS got pretty poor mpg, especially in the city. The cars do well overall - especially the vette.
100k at 14 combined cty/hwy = 7143 gallons
100k at 16 combined cty/hwy = 6250 gallons
= ~900 gallons saved
900 x 2.50 - $2250.
Add in the $3600 in price difference and we are approaching a $6000 difference.
Add in my wife saying she didn't care either way (she had the TBSS in full and the G8 for a time -- and had driven multiple 07-09 Eskys), and the choice was easier for me.....I still respect the 6.2L, don't get me wrong.

I have an 07 6.2 with JBA shorty headers, K&n FIPK and magnaflow catback exhaust and Black Bear tune.
Its fast for a 6000lb ride. even with 7 people.
the tune helps it stay through gears longer (6speed)

I just got into a 6.2 last week from a 5.3 with mods. Im not a fan of the AWD.... lets say your at a dead stop in a turning lane about to turn into your favorite gas station. Mass traffic so your going to have to cut someone off so you can go get your redbull and smokes so you gun it. The front end LIFTS up (i cant see any more now) the steering wheel wants to go straight (and theres a curb). Still dont know how I made it.
On the interstate this thing is an animal. It would leave my 5.3 standing still. The rumble at idle sounds good though its stock and the gas mileage is almost the same. The only serious complaint I have is the transmission. Im not sure if im not used to it but it seems strange. I could be off the gass rolling 30mph then get back into the gas and feel like im in 1 gear to low. Other than that its a lot of fun

I have a Volant CAI, volant supertips and a magnaflow muffler and no tune. The idel is a tad rough, but when you stand on the gas and leave "faster" cars wondering what the **** just happened, the look is priceless. Huge whine out of the cai and the thing moves out. I am averaing 13.1 mpg according to the trip computer, nut do not really care, you do not buy a big SUV for gas mileage. It will be at the dragstrip this summer, but it will spin all 4 if it is a little wet out.

I have the 6.2 in my 09 Denali XL with AWD and its quickness will surprise you. I had the 5.3 in my Envoy (although it has about 20 less HP) and I couldn't imagine it pulling another 1000 lbs.
Gas mileage? I averaged anywhere from 17.5-19.7 on the long trips I have taken so far. 17.5 was into a strong headwind cruising at 75mph. The engine is real smooth so I don't know where the roughness comments come from. I do have a 2008 Corvette with the 6.2 and it makes 33hp but it is slightly rougher idle but adds to the character of that car. With the 6.2 in the Denali XL I can go about 550-600 miles a tank. 450 just breaks the 1/4 tank mark.
My guess is that the Escalade feels slower because it probably has 22s instead of 18s or 20s. Bigger rim means more unsprung weight. My Denali has 20s. The AWD in the Denali does hook up real good though.
Also I think manufacturers lower the HP on some models because the rest of the car is not as good. A Corvette's drivetrain is a lot different than a Camaro or GTO, one being the tranny is in the rear. I wouldn't be surprised if the half shafts are different size also.

I love the rough idle in the vette, I only have the ls2, but things a beast, I cant tell the difference stock for stock between the two actually. Plus mines far from stock so it would cream a ls3 and hang with the z06 on the straights.
