    2.0 stuck, hitting a wall for more power

    Looking to push my 2.0 a little further but I hit a wall and cant seem to get passed. The only limiter I see is Turbo FMEM but that?s not until 4900 rpm. I have already increased the turbo airflow limit, maybe I need to up that some more. But my goal is to have more torque above 3000. What I dont understand is that in my 1st log at WOT the car only gets a reported 240 tq and 1.97 air load. But doing a second long moments later while still driving, at part throttle 70%-75% throttle, I can get a reported 265 tq and 2.05 air load at 3400 rpm an holds 250 tq until I let off.
    I don?t log my map points anymore so I can get better resolution but whe I did, at WOT it goes?.
    RPM Map points
    2000 9
    2500 9
    3000 9
    3500 8
    4000 8
    4500 6 7
    5000 6 7
    5500 0 11
    6000 0 11
    Any help would be appreciated. Thanks.

    Looking at the airflow limits for the turbo, it seems like it might be a similar turbo to what the Mustang has... Just a guess, the values are pretty close to the 2.3 stock values.

    As I understand, a "Turbo FMEM" airlimit source is the turbo airflow limit table, so you might just have to go a lot higher.

    Here's my current airflow limits:

    Which are a copy/paste from an HRI 2.3 Focus RS tune.

    So upping the airflow table got rid of the turbo fmem, but the car still feels no better than stock. I noticed that I get more air load and torque is higher during part throttle. In the log, I very slowly increase throttle and as soon as I get into wot, torque and air load go down by about 30 tq. I can repeat this every time.

    Any other helpful tips?
