    Camaro Zl1 Stage 2 Problem tune

    I can not find the solution to solve the problems of lack of power and speed and I think it is because the car is protected because it is not normal for a car with 700hp to run like this.
    Mercedes, BMW or Audi, they look like planes next to me.
    Could someone help me out so I can leave an American muscler car where it deserves?

    The modifications on my car are as follows:
    BBK Performance full length Camaro headers 1-3/4"
    L650182012 Lingenfelter High Flow Camaro ZL1 Cold Air Intake LSA
    L250150309 Lingenfelter CTS-V Camaro ZL1 LSA LS9 10 bolt Supercharger Pulley Hub
    L220300709 Lingenfelter CTS-V Camaro ZL1 LSA 2.55 8 Rib 10 Bolt Pulley
    L960130709 Lingenfelter Supercharger Isolator Coupling LS9 LSA Engine 2009-2014
    8PK1655 8 Rib Poly V Belt CTS-V For LPE 2.55 Inch Upper Pulley Lingenfelter.
    L310065307 Lingenfelter 160 Degree Thermostat.
    Inyector 1050 cc.
    Spark plug NKG TR7IX
    Oil separator Kit BBK.
    Camaro ZL1 35% 10 Rib Overdrive Balancer Pulley Lingenfelter.
    Kenne Bell Boost-A-Pump 40 amp - Supercharged.

    On some pulls you are making 21psi and have negative spark advance, other pulls it shows 4-5 psi. Cant view your tune file.

    seems like the tune file is locked and i bet that negative spark advance is what is KILLING your performance. Also judging by your narrowband voltage looks like you are running a little bit lean on that first WOT pull

    So your log file lacks MANY pids needed to tell what is going on.

    There are two things that stick out.

    First is timing. -6 degrees is a killer

    The Second is MAP. On the first pull it hits 246 kpa, after that 135.

    The two together mean this car would make about 350hp.

    I believe this is the same car HERE
