Hey guys, I'm soon to be a proud owner of an 06 GMC 2500 LLY. I previously had a 6.5 and I just couldn't stay away. I found a great deal on my truck, only 5,700 miles, practically brand new. I have been reading this forum while looking for my Duramax, and was happy to find most of the questions I had while searching already answered here in previous posts.
But I do have one question. I am purchasing my duramax through a dealership. At this dealership there was another 06 LLY traded in where the guy left his superchips flashpaq in the back seat when he traded his truck in. Now I personally have never used a programmer. All the previous cars/trucks that I have owned that I have "chipped" have been flashes/changes in programming to the factory ECM. Now don't programmers, like the superchip, work by swapping your original factory map with the map that is preloaded on the programmer?
So my question is this. What happens if the guy who traded in this other truck that had the superchip left the superchip map on the PCM in that truck, and his stock map is on the flashpaq? How will I know? Before I leave the dealership should I plug in the flashpaq to my truck? Will it try and swap his factory map for mine?
Thanks in advance,
Rob
