I have never checked chain stretch with the tensioner out.

IWIS is top notch stuff, I have used them with great success in all of my vehicles. Even with a new chain and new rails in the 560, the cams were still about -1° late... tossed in some +2° woodruff keys. Now they are +1°, I figure the chain will elongate and I will be fine.
