I have two Keisler products, their TKO 500 and their RS 400.  Both are outstanding and do just what they say they will do so I ordered another RS 400 and here is where the story starts.  Original shipping estimate was 4-6 weeks, then it nearly doubled, then after discussions with Mr. Keisler, it was shortened a bit but that ship date did not happen.  Salesman would not return calls, delay after delay, parts issues, unit failed the bench test and now with the engine out of the car waiting for the new transmission, no idea when my transmission will arrive.  Just about ready to put it all back together and stop the order.  Seems almost like if I want it real bad, that is the way I will get it.  Anyone else having having support/truth issues with Keisler Engineering?

I've heard good and bad about Keisler over time (the Mopar guys hate Keisler with a passion).  My only dealings with them was positive though I ended up not buying from them.
