Do you have AD injectors?

Please turn off the caps locks, it makes it very hard to read.

Thanks!

Sorry I thouht the caps on would make it easier to read ,,, I am not sure what type of injector I have but, they are original for the truck and it is a direct inject turbo if this helps . I need a little help I am so tired of driving with O.D. off so that it keeps rpm up if it shifts into O.D. it does not stop jerking , sputtering ,loping untill I speed up past 53-55 mph or I am stuck driving with O.D off to avoid the annoiance due to the fact that the majority of the roads I travle are 50 mph. As long as it is a 45mph road I usually drive around 42-44 and it will not shift into o.d. and it rides smooth .. any idea's that might I try to alleviate my annoance PLEASE and THANK YOU my feelow ford brothers

Do the RPM's fluctuate when this happens? Does the engine sputter?

My truck did this before I did my injector swap. I got stage 1's and no more miss at low RPM's in OD.
