I’ve a Thundermax on my Stage IV 2018 Road Glide Special and it does a great Job. As others have stated, you will always get the most out of a Dyno tune, but the TMAX does a pretty damn good job with it’s wide band 02 sensors and dynamic tune. TMAX has fantastic support as well.

I've used a Thundermax on highly built Twin Cams and always felt it left a lot "on the table" if you're looking for max hp. It's major short coming is it has no knock retard control ( like the stock ecm) and does not compensate for load -- it's only based on throttle position. No compensation for load/map like the stock ecm. I went with a Power Vision for my M8 vuild and will never look back. Do yourself a favor and get a Power Vision from Fuelmoto with one of their canned maps and you will be very pleased that you did. Thundermax is good for mildly tuned bikes, but for the streetabke high performance builds its a poor choice.

Getting a base map
Hi guys,
have a 2018 FLFBS with a screaming eagle stage 3 kit installed (117 with SE498 cam, 11:1 compression) Screaming eagle high flow air intake, Vance and Hines large radius 2 into 2 exhaust. Have tried maps from fuelmoto and thundermax themselves, but both dont seem to have the timing quite right. Idle seems off and not crisp, and power is not what it was before the thundermax install. No pinging evident and have clocked about 700 miles since thundermax put in. Can anyone suggest an appropriate base map to start, would think this was a common mod combination. Think my compression and cam are not reflected with previous base maps. Thanks in advance

With that said, I learned my lesson and now use a PV with Fuelmoto maps.

Don't need knock control unless you are trying to run stoichiometric at cruise on a production smogged bike. It's there to fine tune cruise that is needed due to manufacturing tolerances. Having it, is not going to make any difference at wide open throttle except that it might trigger randomly and you lose HP.
Since the M8s use knock sensors instead of ion sensing (patented by Delphi), thundermax didn't bother using them?
