    those gray box are there in both OS , have the same ECM number but seems not compatible. have to open the compare tune in a separate software and then I can have the difference .

    They aren’t “missing.” They haven’t been mapped into HP Tuners interface software.

    AKA "Missing".

    It's not a permanent thing. Just message support with the strategy and missing parameters and they generally do well to add them quickly.

    for Auto-Hentzschel to say "Roush, whipple or Ford Racing OS comes only with a few parameters." is not true in the slightest.

    It was time consuming but i did not be able to have the car running smooth by merge the roush tune on the GT OS . Throttle was acting very sensitive , and hit the P061B code as soon I did go over 40% throttle .

    I Flash the Roush OS , boom ! like a charm . Just have a Diff Temp Overheating message on the cluster and car doesn't have this feature .

    i also tried to copy Roush tune to F150 OS and got p061B as well and wont stay running. My guess is it has to do with the MAP sensor and ACT sensor that connects to the IMRC's. The code for this has be written into the roush os and is not visible via compare files.

    Best tune in the world

    I have a 2016 GT w/ Roush 727 kit and with the only engine changes being ID1050X, Return Style, no cats. You can try my street tune, it's the stock strat (NOT ROUSH)with a 6R80. The speed density tables are calibrated from an AEM MAP for an 85mm Pulley (8lbs boost) on 91 octane, shifts at 7400-7600. All you should have to do is put your injector info in. PM Me if you think you want to try to copy mine.
