After installing a set of RV275 injectors my truck has started to miss on a hard run through the gears only from third gear and up and I have no idea what I could have done wrong. Any ideas would be very helpful.

 

Maybe some air getting into the fuel

 

Sounds like maybe you need a pusher pump. Sounds like its running out of fuel if it only does it in higher gears.

I have a holley blue pusher pump that I installed about a month ago when my injector pump went out.
