    E550 m278 adjusting for boost tables

    I am working with my local tuner on my 2013 E550. He has much experience utilizing hptuners on many other platforms, but has found it challenging to adjust for boost via the wastegate tables. Regardless of how much kPa he is demanding, it has no affect to the vehicle. He also says that there are less adjustable tables on the m278 platform then there was on the recent m156 c63 that he tuned prior.

    Can anyone direct me to the correct tables and method need to make the adjustments to increase boost pressure? Im under the impression from some of my reach that torque management might have some part in the adjustment.

    Boost will only increase in response to a higher torque request. Here are most of the tables that need to be modified:
