What style injector for 2013 flex fuel?
 
im in the process of adding a procharger to the truck and now I need injectors. From what I can find I need the ls3,l92,l99 style. Will these fit and and will I need any adapters for height or connection style? Thanks

Your current injectors are 50-52lb at 58psi. That should support an out of the box Procharger.

Once installed, log your IDC and see where you are.

If he has a 6.2 they are that size. My 2012 flex fuel truck has 38lb/hr on a 5.3.

I'm going procharger as well and from my 2nd grade math that says I'll be near the max power output on 6-7psi or 360-380whp. I'm looking for that extra 100whp bump for the time being, then switching to 6.0/6.2 flex fuel injectors because they are cheap.

I have the 5.3 engine

I maxed out my 6.0 FF injectors with a vvt cam. With my turbo at 8 lbs I was hitting 140 IDC. Upgraded to FIC 115lb @58 psi injectors and I hit 44 IDC at 12lbs now and surprising my FF pump has yet to hold me back. So those injectors will max out quickly, save yourself the headache and upgrade. How much is a set of 6.0 FF injectors going for these days?

Good to know. I have the 6.2L L9H with stock FF injectors/pump and after the usual bolt ons I want to do TVS supercharger and cam. Was wondering what the limitations of the fuel system would be.

I'm running an S475 on a 6.2 L9H. I'm maxing out my stock injectors at 7#. I went with FIC 1000s and will be running E85 at 12# once the injectors are in. My tuner was running a similar setup on his 6.2 and never maxed out the stock FF pump.

Wanna sell those L9H injectors when the new o es come in?

Are you asking me or the OP? I’d be willing to sell mine. Make me an offer.

Bumping this rather than starting a new thread...

O.P. - did you ever end up getting bigger injectors?

Does anyone know what length the L9H injectors are? Im finding conflicting data on the interwebs while shopping for some higher flowing ones. Different sources say ls2 length while some say ls3 and others say to pull one and measure to be sure. All sources asked "should" be very knowlegable in their products for ls engines, but i dont wana order the wrong size.

Was hoping someone on here would know 1st hand.
