Ecoboost downshifting

[emm5504]

I recently installed the MPG booster tune on my 2013 fx4 ecooboost and whenever I get on the throttle in 6th gear it starts to down shift. Any ideas of how to fix?

if you apply any decent throttle, it should downshift...or it will lug the engine, maybe Im not following 100%?

Thanks
