Should I get new injectors for my new setup?
Okay, I've got a bunch of parts waiting in the wings for install. Do I need bigger injectors for new setup? Or should I just have my stock injectors cleaned and flow tested?
Ported and siamesed plenum
Arizona Speed & Marine SS runners.
TPIS Big Mouth Intake base, as cast.
Ported L98 heads, 2.02 intake, and 1.6 exhaust valves. Set for .550" lift.
Lingenfelter 74211 camshaft. 211/219 Duration @ .050" .500"/.525" lift. 112* LSA
Hooker 2055 headers and Y-pipe.
American thunder 3" exahaust with Flowmaster 80 muffler (waiting to swap the muffler for a magnaflow straight through. Hooker aerochamber would be good too)

Yeah you're gonna be able to pump out a lot of air now, so you're gonna need some more fuel to go along with it to give you more hp. I would suggest bumping up to some Ford Racing injectors and while you're at it, get an adjustable fuel pressure regulator. You're basically going for a huge setup off the bat so I'd suggest going somewhere around 26-30lb injectors. 24lb injectors are more common and would work, but you'd be limiting yourself. Custom chip would definitely need to be made as well.

I left out all the little crap in the list. Didn't feel like listing every damn little thing like gutting the air box and such. In this post I am concerned ONLY about the injectors, so leave the rest out of it.
From what I've read the stock 22's should be able to supply enough fuel to meet the requirements of my engine. However, the injectors do have 100k on them. So I really want to know is, is it worth having them cleaned and benched? Or should I avoid the trouble and pick up a set of SVO 24# injectors.
