Depends on your HP goal.
Do you just need bigger injectors or whats the issues with the current ones?Originally Posted by mychevyisntheavy
whats the vehicles/engine combo?
Cam specs
what intake are you using?
What fuel pressure and is it a referenced fuel system or not?
What injector connector is currently on you engine harness?
I know youve posted on here a bit the last few months or so, but i dont remember your setup or anyone elses other than mine. Im sure its the same with the other guys in here. And yes, i could go through your old posts and look, but no one wants to do that. Sorry, im not trying to be rude at all, Im just pointing out that its the OP's job to layout the basics of the vehicle youre posting about for the benefit of the people helping.

We cant tell you anything without any input from you.
help us, help you..
He's had decapped injectors, then some Bosche's that the supplier has (maybe) been uncertain on. Plus, maybe another set that didn't behave.
Deatschewerks or FIC that have good GM injector data.
This!
Ill vouch for FIC(connection) ive always gotten good stuff from them.
I have tuned both with great results. Just finshed a TorqueStorm tune on a 5.3L using 91# Deatschewerks. Has a stock idle and excellent tunability. Went with the larger injectors because it will likely get a lot of other changes and E85 in the future. For now it is a bone stock 250K mile 5.3L Avalanche with 12 psi on it.
Fugg yeah!
OEM GM Flex injectors are also a good cheaper option (Buy from reputable source!) , not sure what size is right for your build but there are OEM options up to around 50lb, check out the 12613412, data in Gen III format is also readily available
I put 3 sets of these in last week and tooned the trucks with them. They flow the same as the ones we were getting off ebay that were way cheaper.
