Holley 522-108X Injector Data for GM?? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

SSFury · 01-19-2024, 09:31 PM

Hey all. So I bought a BTR Intake, a Nick Williams 103 TB, and Holley 522-108X 100 pound injectors to do an intake swap over tomorrow. Tonight, my tuner reaches out and says he cant do it, cause there is no GM Data for the HPTuners device for Holley's injectors. Granted, they are cheaper than most injectors, but they're still $400, and Holley's a good brand. Unfortunately, they want you to buy ALL Holley stuff. I've been searching, and searching, and I can't find any data to be able to give my tuner. Does anyone have any secret saved data files, or know any secrets I can share with my tuner to be able to use these injectors? HPTuners is a worldwide brand, and Holley makes good products, and those injectors are made for GM engines. I dont get how I can spend $400 and not be able to use them. Help!!!!

You should either call Holley and ask them what data to use (which they will probably say to use GM data) or return them and get some Fuel Injector Clinic's injectors because they actually come with data and is also provided right on their website but, they are about twice as much. I'm assuming that your using an email tune correct?

Yeah, email tune.

Looks like you aren't the only one having problems with data.

Personally I think your going to spend more money on tuning to make them work than what a mainstream set of injectors would cost. I am a big fan of Injector Dynamics you pay more but they are worth it.

The reason I ask is because if you do a dyno tune somewhere they can get them to work I believe without the data. But I know that probably isn't feasible.

I'm still running my stock OEM injectors in my setup. Never had any issues as of yet.

You can get them to run without GM data at wot. Getting them to idle and cruise well without GM data will take a real good tuner willing to spend a lot of time fighting them. Get injectors that are confirmed to have good GM data before purchasing.

And GM data is about 4(?) different things.

And this not an issue with the quality of Holly injectors or HPT. It’s an issue of how oem GM computers work.

Thats for the inputs, all comments are accurate and insightful. We took the car to redline to test Duty Cycle of the stock injectors, and I was only at 60%. So I'm keeping the stock injectors in it for now, and bumping them up another 20%. Will definitely be getting better injectors when 80% is no longer good enough.
