I just installed a BD Cool Down Timer this past Saturday. Well this afternoon when I got in, I turned the key off, truck stayed running like its was suppose to. Then when it did turn off, it was violent, my truck shook bad. And when I went back to the truck the LED light on the BD Timer was still on(meaning the EGT's was still higher than I had the Timer set to cut off at). So it cut the truck off before it needed to. If any of you have one of these and have had the same thing happen please let me know. Cuz I almost want to take it off now....
