File for 99 vortec 5.7 manual c1500 OS 9365085
Looking for a stock file from a manual truck so i can compare settings and what not. I have the engine in my 77 nova with an lt1 t56, i have ran into an issue were it has very bad revhang, holds 2000rpm for about 3 seconds in between shifts. I want to figure out how to stop this from happening.
PCM and engine are from 99 gmc yukon 1500
Thanks
