Your buddy's truck sounds sick. Haha. And it sounds like we are both having the same problem. I'm on the hunt for a new harness because my daily (03 Tahoe, swapped the 5.3L for a baby-cam 6.0L last year) is having some weird sensor issues... Looked into it and found the engine harness wearing on the steering shaft/column between the header and the frame rail. Given it's my daily... I don't want to deal with buying a used harness to save a buck, only to wind up having to troubleshoot/repair after installing it. Would rather spend a little more and make it a one and done experience.
Only issue I can find is that the TSP harness has EV1 style injector connectors... And mine are EV6. So I'm really going to be in it for the harness plus injectors. But the TSP harness is almost half as expensive as the alternatives, and my injectors are OEM as far as I know, so maybe it's a good time to remove/replace to make the new harness work. I'd like to size up on the replacement injectors as I have dreams of throwing a blower on this truck one day (like your buddy) and would like to have some headroom in the fuel system for that.
To that end... Does anyone know if I'll have to adjust my tune for a bigger injector? Is that something the fuel trims will just work out on their own or will I have to go in and actually change some of those tables? I would assume that's a big enough difference that my tune will have to be adjusted.
