Default GTP Injectors..36lb
What do the stock GTP 36lb injectors flow at on stock LS1 fuel pressure? Found a set for cheap and would be a cheap, nice upgrade over my stock 28lb ones. I just need to know what they flow for tuning purposes.

If you look on HPT forum there's the calibration numbers somewhere on there for the GTP injectors.

Do you have a link? I dont have HPT anymore so I cant log into my account and search around but if you can find it for me and provide a link I can send it to my tuner and he can update my file...I would greatly appreciate it.

Tell your tuner to go look at an ASA motor PCM file. I've also posted them here many times. Try searching.

The GTP and ASA engines both came with the white Bosch Design III 36 lb/hr @ 3 bar injectors. They are a direct fit into any Gen III engine with the appropriate PCM tuning for the larger injectors.

Here are the injector tables: 36 lb/hr @ 3 bar Bosch Design III

copy of one I did, Looks better in excel spread sheet, working on getting these installed when the wideband is in. I'm told there is a lot more to it than plugging those numbers. Still trying to figure out HPTuners myself.

Are these the only tables that need to be changed for these injectors?
What about the small pulse and minimum pulse tables?
