Hey guys, Looking for stock tune for a 1999 K2500 Suburban 4X4 (Autotrac) with the 5.7 and 4l80e. If it has 4.11 gears and the 42 gallon tank that would be great too. I checked the repository and there is a C3500 but doesn't quite match up. having some issues with speedo, fuel gauge, trans shifting, etc.
Been working on this low mileage vehicle for some time. Was told it had a blown motor by the PO. Turned out to be a cracked flexplate. Someone went crazy cutting the harness and deleting emissions components and messed with just about everything in the tune. Ive managed to piece together everything and have it running and driving with no CEL. It does have a couple issues shifting and a few other odds and ends. Ive looked at multiple other "stock" tunes for the 5.7 or the 4l80e and when i compare to what i have there are always differences... At this point i think i'm done so i'm hoping someone can help with an original stock tune for a similar setup.

Appreciate any help!!!
