One thing now that the 800HOs are getting miles on them, the EV cable will stretch and cause issues. The actuator will operate correctly, but the valves will not open all the way. I high recommend changing the cable every other year. It's really easy to do and doesn't require a relearn. Last time I bought an EV cable it was around $30. FWIW, when I did the BMP 860 kit in the summer of '16, I had new cases, the original cylinder block and new exhaust valve kit. Just out curiosity, I had the dealer do a relearn and the tech came out and asked if I was having problems as all were with in specifications. Fast forward to the summer of 18, the 860 came out and my spare 800 was put back in along with a turbo. It had the original cases, new crank/rod kit, new cylinder block, original exhaust valves with a new cable and never did a relearn, sled will pull 8300 all day and I've not had any issues with it. One more thing, the EV cable can and will break without you knowing and will not throw any codes but the engine will not rev over 6800-7000 RPM. Only way to check is to disconnect the cable from the actuator and pull gently on the cable.
