    Time Attack - 08 Denali Acceleration Performance

    Hello Everyone, I had a chance to do a time attack run with my truck and log this run using my Racelogic PBox. For those who are not familiar with the PBox, it is now a universally accepted standard for measuring vehicle performance against time. The device installs via suction cups on the...

    New Here.....help me with ideas for my Tahoe

    To be honest, powder coating is great if the area being treated sees rubbing/friction/frequent handling etc... which the bumpers are not. I would paint to match and clear bra and be done if I were you.

    New Here.....help me with ideas for my Tahoe

    Gorgeous truck. Well done so far. In which direction are you going with the grill? If black, then I would suggest you maybe black out the trim on the front and rear bumpers too. See if you can photoshop it to gauge how it would look.

    I Couldn't single a truck out this time around. I ended up voting for three, any of which I'd be proud to have in my driveway.

    x2. :Handshake: I think I'm going to try this out and maybe fiddle around with a cutout. Cutout closed, flows through both mufflers; cutout open, bypasses the second muffler.

    Where did you find space to put two mufflers and a resonator? Do you have pics of the setup?

    2008 Denali Goes Much Much Faster!

    I have no direct experience with them. I ran a google search and checked a few threads out. From what I've read they seem good. Super cheap as well. I just wonder if the age old saying of you get what you pay for applies in this case. The industry leaders such as ARH, Kooks, Dynatech and SS...

    Fast what did your 6.2 dyno at before the tune?

    2008 Denali Goes Much Much Faster!

    Absolutely. Remember also you quoted rwhp. Mine is awhp. Much higher parasitic loses in an all wheel drive car between crank and wheels than a rwd. Like I mentioned, stock 2008 makes about 280 awhp on this dyno in similar conditions.

    2008 Denali Goes Much Much Faster!

    As Jenna mentioned, the numbers you are quoting are crank hp. A stock 2008 Denali would dyno around 280 at the wheels on this dyno with the way the guy has it set up. 2009 up Denali is slightly higher as GM increased output to 403 crank. Achieving 350 awhp is a jump of about 70 horsepower at...

    Thanks for the heads up. One last 4th gear pull with the final tune and that's it.

    2008 Denali Goes Much Much Faster!

    :Grenade: I thought 4th was the standard gear for running the 6L80... When I get the final tune installed I will run it again in 3rd and in 4th just to have a base comparo as I do not have 3rd gear runs to compare against!

    Remember this is with Justin's initial tune. I am hoping he can tweak in a few more ponies for me.

    Not hard. On a lift with someone who knows what he's doing, it would take about 3 to 4 hours. I bought the headers direct from ARH. I emailed the president/owner of ARH and he did the deal direct. Great guy, very passionate about motoring and about his products. His email address is...
