    What MAP sensor is installed?

    The log shows it pegged at 105kpa with the key on engine off. That tells me the data is wrong for the that sensor.

    No idea on the throttle body module stuff. Sounds like a giant can of worms.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    The LSA map sensor data is 312.50 and -11.25. You'll need to correct for that.

    I mean drive by wire is fine but you could make all the power that stock engine can make on the stock 78mm throttle body. Going to the 102mm is purely for looks and or flushing money away.

    we are running a twin turbo setup i told him we coulda got away with a 92mm and it woulda made tuning a touch easier but the new motor will be a 408 stroker so it was just a spend money once kinda thing.

    those are the numbers going in for MAP linear and offset yah ?
