If I buy a used one....Will it work...I bought another brand used and it would not work because the owner did not hook it and uninstall it from his truck....so it would not reprogram my truck..
I would not buy a used one because of what happened to you the first time. Besides the one im using is old and out of date. Go to superchips.com or diablo programmers and buy a new one that is up to date. Hey please subscribe if you have not thanks.
No does not effect smog results but when I take the truck for emissions I remove the program and put the stock program back on. Hey please subscribe to my channel thanks.
Silveradoman61 awesome I bought my 03 Sierra single cab and it came with the exact same module. It's in stock settings right now but when I have the gas money for 91 grade I'll install the performance setting. U got urself a new subscriber👍
