    I believe the brake torque limit is should be set to "Enable" in the tune as that allows the TCS button to disable it when actuated after start up.

    Sounds like someone messed up and disabled the brake torque limit in your tune.

    I have no way of reading that yet. Plan to purchase HP Tuners soon.
    Another issue I have had with it since I bought it (with stock and Circle D stall), sometimes at a stop, in drive, the car will sort of lung forward simultaneously with the loping of the cam. Really kind of hard to describe. Today I noticed, as I eased up on the brake pedal, preparing to leave from a stop but not in motion yet, from firmly pressed to the point it was about to let the car move, that it started this. Was thinking maybe it has something to do with the engine not having enough vacuum, because of the cam, to operate the brake booster. While idling, I pulled the vacuum hose from the booster and blocked the hose with my finger. The engine lope smoothed out as if maybe the brake booster is leaking. I'm thinking the burnout problem may be due to a drop in engine vacuum while pressing the accelerator, which is taking vacuum from the power brakes, and in turn making the brake pedal feel harder or as though it's releasing. Didn't have time to troubleshoot, as I was leaving for work. Will check that tomorrow and update if I find something.
