Don't exactly know where to put this ?

While checking my fuel issues a few weeks ago I noticed on my Predator that desired vs. actual mpa was real close at idle and normal driving but at WOT actual dropped about 20 behind ( like 152-155 desired might be like 130-136 actual) !

After installing my lift pump last weekend .......I checked again and there was no change !

Should they be closer at WOT with my set up ???

I still have not hooked it up towing ........which is where I have been running into trouble with limping before I installed the lift pump !

yeah they should be close. that is what mine was doing. except with a tech 2 you can command the pump to full pressure and compare the commanded, and actual. mine only got to about 125-130. had to do a pump

A CP3 pump ?

Like I said.........just installed a single lift pump........still 130's !

Have you done a bottle test yet??

yeah. unless their is major resriction, but like you said you have a lift pump. have you checked your fprv

Still have not done the bottle test.............I know.........I know !!

I tow my boat and my father in law has used it the last 5 weekends in a row ! And it's the only time I have a problem ! I am going to hook it up this weekend and bottle test it !!

With a properly working lift pump and a fuel filter that isn't restrictive and a FPRV that doesn't pop you should be able to hold the pressure with the highest Predator tune.
