Easy ordering and delivered on time… Easy ordering and delivered on time (about a week). 1997 K1500 had a check engine light with P1406 code, and troubleshooting ruled out all other components. Perhaps the computer was not allowing enough time for opening/closing of EGR pintle. R2 computer and all is great. Thanks!

PROTECH VERY DEDICATED TO THE CUSTOMER Protech sent out an ECM that was bad. They immediately sent a replacement which also did not function properly. They immediately followed u with a third unit that works properly. Have to say that they bent over backwards to make everything right. I HIGHLY recommend PROTECH for your ECM replacement needs. They personnal were knowledgable, helpful and very customer friendly. If I ever need any additional ECM's they will be my GO TO source. THANK YOU PROTECH.
