I left a post in the obd1 forum but thought it may b a better bet to ask over here. I just installed a 2000 model HD3500 Intake on my 89 C3500 and a cant find the offset for the injectors. I'm using the stock 17109596 Injectors but can't find any info on them. I installed a walbro 450 lph pump at stock pressure atm. Is there anyone that could shoot me a link or have the means to look in a bin for that truck? Pleeease? Or I can haunt the pull a part yard for LS injectors?
I would so appreciate any help or advice!

Gearhead-efi link with a .bin file for a 1999 454 http://www.gearhead-efi.com/Fuel-Injection/showthread.php?1510-1999-TunerPro-Bin-Files

Not sure if 1999 is the same as 2000. The 2000 gearhead-efi .bin file library did not have a file for the 454.

Maybe Univeral Patcher will open the 1999 .bin file: http://www.gearhead-efi.com/Fuel-Injection/showthread.php?9616-New-LS1-Tuning-Tool-Universal-Patcher

perhaps this helps

(yes, its HPTuners, but you can download and install HPT for free and read the file)
