Alright
Truck: 99 f150 with 5.4
Existing mods: Cold Air Induct, Edge Evo, Underdrive Pulleys, Mark VIII Efan, 2.5 in. True duals with 2 maggie high flow cats, X pipe, and Dynomax Bullets.
Would going to a bigger injector besides the stock injectors help with performance? If they would what size as far as lb. per hour and what body style are the existing injectors? In other words what would work? I plan to be getting plugs changed soon to the IT-16 Densos and just figured hmm the stockers got to be old and if I used Ford Motorsports products what size should I get? I paln on forced induction, but I dont know for sure because of the money it costs. Thanks alot fellas, I did search but mostly came up with questions as to cop's and fuel injector problems..

 

larger injectors would require another tuning device be purchased


and no reason to go larger until you've added some boost (ask me how I know)

 

awesome, Im glad you cleared that up for me. I'm tryin to squeeze as much as possible without dropping all the cash on a forced industion setup yet.

 

Now if you get some head work done or add some boost, then yes, larger injectors. Stock engine? Stock injectors.
