"Picture of Dyno sheet included in pics" I'll be going to the track to compare with last years run of 13.84 @ 103 1/4 mile, stock engine and internals just a tune and CAI on E85.
    BUILD list:
    New LDK block "stronger Gen 3"
    Forged Pistons
    4340 Rods
    Stock head "not ported yet"
    82# springs and retainers
    Stage 2 cams with Fuel lobes for E85
    3" downpipe
    Resonator Delete "before build"
    Stock mufflers "Free flowing, Quiet, do not want loud Ricey exhaust, want a Sleeper, loud enough when you get on it but no Drone when cruising."
    EFR/ZFR 7163 Turbo swap "running 24psi"
    Front mount intercooler with all piping.
    Flex fuel sensor added
    3 days of Dyno tuning.
    "First 13 Auto built to this level caused a lot of tuning issues, but was able to over come the Torque management. ZZP still only charged $150, They used my auto GS as a guinea pig for R&D for future Autos. 11&12's are not able to make this much power, Different TCM and will only make about 360whp. So ZZP was able to learn a lot from the build and Matt was able to tune it to make the most of the build.

    Here are some links to the dyno pull, and 2 other street pulls, one from a dead stop and light brake torque/boost building, and another doing a 40mph pull.
    Dyno pull:
    Street 0-100mph pull:
    Street 40-100mph pull:

    Thanks, Was basically a Guinea pig for others, but posting this I'm sure helped others with their upgrades, and it can be done with a least 2013 it can. I'm really happy with the build, can't wait to hit the strip again. I'll keep ppl posted with those numbers also.
