    Not sure when it will get installed but I have worked with Flashmaster products before and they have always been spot on. Looks great, packaged great and received very fast.

    It took several tries for me to get it programmed right, once I installed it, but now it runs better than it has in several years. Would recommend this seller to anybody needing a replacement ECM.

    Very fast delivery and after about an hour of time to program several keys, the truck is back to running smoothly and has stopped throwing codes. Good price for the level of problems solved.
