I was wondering I have read alot about the v8 swap in these trucks and they say it is pretty easy they say you just need the V8 harness and 24x LS and the 4.3 computer retuned, well last night I realized that I still had the HP tuners so I tried it on the truck it worked, I noticed alot of stuff was disabled can I just add the component and enable it in the computer like the factory silverado electric fan that I don't have.
