Chip question

[Bob Howard]

I just checked the chip. From what I see, it appears to be stock. Would like to confrim this or not. The 1 to 4 still works !!! The only information on it is:

AYBK 1616 3905

Blue in color.


Thanks for your help.

you have a 90 chip. the fact that the 1-4 lock out still works, leans to it being a stk chip. if you have a tuner ,he can rewrite that chip to improve your performance.there are 2 good tuners corey henderson and mark haibeck

Thanks, thought it was stock. Mark is in my area, about 30 miles north.
