Squirted and tested the Hess tune this morning. 91 octane, level asphalt, 50 degrees, turf mode, warmed up to 2 bars, no WOT warm up runs--squirt and straight into 5 runs each, 0 - 40 mph: 2 in Sport mode; 2 in A/T mode; and a final run again in Sport mode. I used a stop watch which seemed fairly easy/accurate - has to be better than a smart phone app.
Stock: Sport mode - 7.31, 7.10, 7.00; A/T - 7.00, 6.87
Hess: Sport mode - 6.88, 6.94, 6.90; A/T - 6.78, 6.71
Stock average: Sport mode - 7.14; A/T - 6.94
Hess average: Sport mode - 6.91; A/T - 6.75
Hess was about 3% quicker and 30 degrees cooler at the hottest part of the muffler between the bolts on the exhaust port flange, using an IR thermometer. Hess shifting was firmer and I definitely like the shift pattern for my trail riding style. Down shifts were a little more aggressive, which I like.
The machine ran great and the Hess tune will definitely do. Regular A/T mode was quicker . . .hmm. My P1K5 is 2100 wet with +10# per corner over OEM wheels/tires. I suspect I'll try another PV3 tune sometime soon. I know of the COPS and FLHoghunter options for trail riding . I am not interested in pushing the envelope and damaging the motor. Like everyone, I am intersted in a lower low range, but that's a different thread.
