    Ok gotcha, mine is 6 speed auto, so irrelevant. Looking forward to getting the Autocal and letting this beast rip!

    Ordered BlackBear Tuning AutoCal, have questions

    So I just ordered a Blackbear Autocal and I've seen where some have had the Tow/Haul button changed to be a "sport" or different performance setting? How does this affect the factory Tow/Haul settings? Such as engine braking while towing, etc..etc. Will I lose those factory towing features?

    11 second Yukon XL Denali 2wd?

    @randeez thank you! That is all very great information! I may need to re-evaluate what I "need". It may make more sense to me to shoot for a mid-12 second time. I tow a 5k lb boat regularly and want to maintain that ability with some cushion.

    11 second Yukon XL Denali 2wd?

    Maybe another forum would be more helpful. Let me ask in a different way.... What mods have YOU done specifically to make 700 rwhp in your 6.2 Denali? Looking for experiences here.

    11 second Yukon XL Denali 2wd?

    That's very helpful....thanks. Anyone else have any tips? What would you do specifically to double factory hp but maintain daily driver reliability?

    11 second Yukon XL Denali 2wd?

    Well thank you for that. So what mods and $ would it take to make "700+ hp"?

    11 second Yukon XL Denali 2wd?

    I'm interested to see everyone's opinions on what it would take (mods and $) to turn a stock 2013 Yukon XL Denali 2wd into an 11 second daily driver. Requirements: Must maintain towing capacity & auto level suspension feature Must maintain daily driver reliability No race gas....93 oct or E85...

    Which aftermarket rotors/pads for towing and better than OEM performance?

    I'm going to disagree on the stockers being up to the task. They suck. I'm not looking for "last a long time". I'm looking for better stopping power/performance....hence the thread title "...better than OEM performance."

    Which aftermarket rotors/pads for towing and better than OEM performance?

    My OEM rotors have some pulsating pretty bad from warped rotors when I'm coming to a stop. So I am going to replace them with new. I will be towing a decent sized boat and occasionally a Jeep/off-road truck on a trailer for long distances once or twice a year. I want a brake setup that will...

    Stream Audio only to stock stereo - Crux BTS-GM1X

    Grrrr... you're not alone man. Just bought this for my 2013 XL Denali....same thing. Nothing behind glove box, XM tuner built into the radio itself. Lame. Guess we're stuck with an AUX cord until i replace the whole thing with an Android solution.

    Shutter/chattering Trans or converter?

    Update: The shudder came back even with Dr Tranny Shudder Fix and Lubegard. BUT....just got a Range AFM Disabler until I can save up for a BB tune.....no more shudder. So what I thought was the torque converter was actually the 4cyl to 8cyl crap. No more hesitation when pulling away from a...

    If you have the auto-level feature, what do these bags do?

    '13 Yukon XL Denali 2wd 1/4 mile times

    But that link specifically says "Will not fit models with factory auto-leveling option." I'm not sure what they would do for me anyway, even if I didn't have auto-leveling. How would "stiffening" up the rear spring help me launch better when I'm not getting tire spin on launch anyway?

    I have the airride auto level thing stock. Is that what you're talking about?

    '13 Yukon XL Denali 2wd 1/4 mile times

    I tried a 1500 rpm launch and it didn't like it, 2.5 60 ft, but still no tire spin. Remember, I don't have a tune on this truck, so all the torque management crap is still in play. I think once I have that, I'll be able to do better. RWD though, so i'll be fighting tire spin too.

    '13 Yukon XL Denali 2wd 1/4 mile times

    Yes, AXN axle code, 3.42 gears I cut a 2.3 60 ft every time, no tire spin, just punching it from idle.

    '13 Yukon XL Denali 2wd 1/4 mile times

    So my gf and I were bored this past Friday evening so we took the Denali out to Orlando Speedworld 1/4 mile track and made some passes. I was really surprised how well this big old heavy beast did. It went 15.45@92 with a 2.3 60 ft. Ran the same thing 3 times in a row. It's bone stock except...
