    That was zero'd out from the factory. We did set it to 20 with no joy.

    We moved the race car out of the way to make room for the Van on the lift

    Is it demanding more? Driver demand not 100% and boost desired higher than actual boost?

    It's likely maxing out the turbo. Depending on generation, you can put a bad news racing actuator on and recirc valv. That will hold more boost and leak less boost. Will require adjustment / retuning though obviously.

    according to this thread,I think it may be limiting by my max engine torque,I decide to rasied my virtual torque 10% to see what would happen

    My DD table must use crank torque because the default is very low ~131 at WOT. It's 276 now. Can't wait for the rain and cold to stop so I can get back to testing.

    ordered efilive. Since BNR sells tunes on that platform, I'm guessing it actually works for my Vanderhall.
