    09 Hummer H2 3.6 KB blower, throttle closes on dyno

    I have a 09 H2 with a forged 6.2 and a KB 3.6L blower. I have a good start on the tune but when trying to finish it up on the dyno today it will not pull past 4800 rpms. As you can see in the log it hits 4800 rpm and the throttle drops to 42%. I am running it with the front driveshaft removed and locked into 4wd. I have attempted to pull the VSES fuse to remove the stabilitrak to no avail. I kept the information short if any additional information is needed please let me know. Any recommendations?

    Tune file and log is posted below. Thanks in advance!

    EDIT> Hitting the speed cut, sorry everyone I am an idiot! Making things harder than they should be!

    Got pic of motor setup? I adapted a 3.6 KB to my Silverado so I'm always intersted in cool swaps like yours.
    Gray Ghost- The abomination. 2007 Chevrolet Silverado CCSB. 98mm turbo, nitrous, 428LSX, Rossler 80E with a brake. Finally finished. 23 psi, no numbers, Slow as hell.

    PBM G8- Aluminum 364, twin Precision 67/66 turbos, 6L90 trans swap, CTS-V/Vaporworx fuel system, slowly making progress.

    Dads 2011 CTS-V- Stock bottom end, stock heads, LS9 cam, pullies, ported blower, ported TB, D3 goodies, and lots of nitrous.
