Rocket3Pilot
Supercharged
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).
Same for me? Other side of Virginia. Almost set up a trip to PA but after talking with the guy who had tuned 3 or 4 Rockets, he talked me out of it? He claimed that the PCV was not really tunable in and below the cruise range and that AT was doing the best I could get already?
Lot's of Harley tuners that say they'd give it a try though, HA!
