No help here: Like "ice cream taster: it's a great job if you can get it" -- I've searched high and low for a tuner, and the hard part I've come to realize is like many worthwhile things in life, tuning is an art, and are often is an iterative process, and the couple of folks with whom I've checked within 500 miles from here who seem to know what they are doing, don't have experience with the Rocket, and being up front say something like, "It's a $125.00 per run, and it could take four to six runs, and well, it could get expensive." And +1 @R3Tex about "PCV is all any of them know anything about".
I'm going to try the
Dobeck AFR+ upon the endorsement of @Idaho Red Rocket 3 (apparently, the folks used him for testing their product, so there may be a chance of it working as advertised).
