Today im doing about 60 and the truck just shut off out of nowhere. Im wanting to think cps because ses came on then after killing the switch and turning it back on no ses light. It happend as I was turning my chip up. Noticed it slightly shaking off and on at idle earlier today. CPS or no?
TS6POS chip, AEM cold air intake, 5" MBRP duals, ISSPRO EGT Boost and Tranny gauges, CFM intake manifold.

 

my 6 pos. chip would do that if i switched tunes really fast, so that may be your issue also, check your connection on your PCM to see if it needs cleaned a little more or if you've cleaned it too much and see a lot of copper, hope this helps!!
