I need to see if I have a stock chip in my truck or not. is there numbers on it or what? How do i tell what i have? I will be checking it this weekend.
It's in the upright corner. The latest stock one was #841 if I'm right. My Sy came with a #3971. However there were ID's (for example #831) which was used by both factory and aftermarket apps. Anyway, check the number first. I guess you are hoping for a stock chip. That 13.47 is quite impressive. :wink:
Do you have an aftermarket boost gauge? Most of the early aftermarket chips raised boost...
