my truck started acting up after i took off the 60lb injectors and put the stock 24lb'ers but left the walbro 255 intank pump on it..
would the fuel pump mess up the fuel injectors and pressure going to the engine. thanks

 

Did you change the tune when you changed to smaller injectors? The pump wouldn't make a difference.

 

yeah i got it retuned .. like the truck has no ***** and like it wants to die when you kinda rev it up on park.
