Hey guys,

This is my first time posting. I'm just starting to work on getting a map together for an engine swap in my girlfriends old truck. its basically a stock 5.3l vortec from a 2001 GMC Yukon with a mild cam running on a Haltech elite 2500. for the initial start up we have the stock 28lb/hr injectors but I seem to be having trouble finding the injector dead time (offset). maybe someone on here has that data in an old tune file? Thanks in advance

Maybe it would help to post the part numbers of the injectors. Easier to find data for them, then.

i should have thought of including that info haha

it an AC Delco injector p/n:17113698

replacements can be found here:
