I have this 2003 Silverado I bought for 3k. It has a ton of issues. This truck was a v8 swap. The computer says it is out of a 03 Yukon xl. However I want to ensure the computer is reconfigured right so I’m trying to figure out if there is a way I can pull the vin off the block or something that will locate the Vin so I can reconfigure the computer to the engine
My suggestion is go buy a V6 and all the fixins and just replace it back to stock.
Or I would also suggest have someone retune the truck so that the PCM is reading your truck's VIN instead of another truck's VIN. Obviously whoever did this swap has a monkey brain.
