01 f150 lightning swap...low power
Hey guys, My buddy is working on a guys lightning swapped f150. The guy JUST got it swapped from his totalled lightning into his F150 and since he got it back from whoever swapped it , it has low power. They did a "complete" swap, and nothing looks rigged or botched up but this thing should run harder than it does. He checked for codes with his Snap-on scan tool and it isnt showing anything. Checked the fuel pressure and under a load and to the floor its 50 psi. Looks good. Checked the intake to make sure it wasnt blocked with anything.
In order to get it to burnout on dry pavement you have to MAT the gas. It does, however pull decent from 3500 rpm up. I know its gonna make more power up top like that but damn an 01 lightning should kill the tires from a dead stop on rockytop pavement.
The only thing her found wrong was the Boost bypass actuator had been knocked loose from the bracket, but we fixed that and it didnt help a thing. The actuator is working like it should be. and according to the stock gauge its making 9-10psi like it should.....but its a dog.
Any suggestions.
*EDIT - I just read something about the boost byopass that may help..."boost Bypass elimination"

UPDATE: Found that whoever swapped the drivetrain had the Heat exchanger coolant line crossed up. It was stirring and not pumping, Allowing the supercharger to run hotter than 40 nuns in a pecker patch. Fixed that and got it running cool...goes like a stock lightning should now.

Well the guy got it from who swapped it and I dont know how long he had fooled with it. We got it and we only spent about 1 hour on it over 3 days. But we test drove it about 3 times before finding that. Plus, it has been frickin super hot here...like 105-110 degrees. When i seen that the pump wasnt pumping i about **** my pants. I know how bad of a thing that can be. The truck runs fine and has no issues now though. Thank goodness.
