    Can Am doesnt rise boost

    Hello
    I have a Can Am 2019 with 1000cc injectors and big turbo, i tried to rise the boost but looks like ecu limit the maximum load on it.
    I got 1 bar maximum, when i request 1.3bar, my lambda value is following the target and no knock.

    I rised the torque to load map up to 330, rised boost target to 1.5 bar, disabled the torque limit switch to avoid any limit. Maximum desired load (STD and Max Boosts rised to 250%)
    Do any of you what was my fault?

    in the datalogger i always got the same values like 191% load with a 71% torque, with the wastegate in 70/74% range and 1 bar.

    may be i need modify the "optimum Engine Torque" table Engine load axis, and rise it to have "same" torque with more load?

    Did you log wastegate duty cycle and Throttle angle?

    Yes, wastegate was around 70/72% and pedal and throttle was 100%, no limits or correction on them
