problems with fass 150 after install
 

I have been having mid range problems with my truck since I had a shop install a fass 150. It is real sluggish on initial take off and then seems to have a lot of sluggishness when it gets around 50. The install took place in a shop, and they installed the pump on the passenger side of the truck. Are my problems coming from the extended fuel lines and longer distance for the pump to pull from and feed to? I am at a loss on what could be the problem...:humm:

PLease help:scare2:
