I have had the VOHK 100LL tune on my ‘22 Boost since it was pretty well new. I just switched to the Bikeman tune and picked up 500 RPM with no clutching changes (P-85 setup). The Bikeman is really a monster!
I was never thrilled with the VOHK tune. My buddy and I did the VOHK at the same time. We tuned and clutched one sled and left the other one stock the first night, and the tuned sled barely pulled away from the stocker (on the flat). Fought with the sled ever since, but could just never get it to perform the way I wanted. So finally I gave up. The Bikeman pulls so hard, it’s really at a different level. This is the 40 hp. quickspool tune.
Chase from VOHK told me last year that they didn’t have any update on their tune. Maybe they do now. But that train has sailed for me.
Fought other things in the meantime- collapsing intake boot when I put a decent track on the sled, Silber can just wouldn’t work at all with the tune (lost a bunch of RPM, inconsistent, maybe it would be ok on a stock sled??)
Bonus- the Bikeman tune was cheap!! $600 CAD with their holiday discount. Had a friend with a torque link tuner flash it for me.
This is all just my opinion and my own experience. Not hating on VOHK or anything, lots of cool stuff about their tuner (EV and wastegate relearn, data logging), they were really nice to talk to, but in the end, it’s all about performance for me.
I should also add the caveat that I am not running the Bikeman clutching, nor did I run the VOHK clutching for long. I believe they changed their spec afterwards. Also, Bikeman wants you to run one of their cans with the 40 hp. or 40 hp. quickspool tune. I did get their can. And it is pricey.
