Looks like a Rocket III (i.e. not Rocket III Classic) but with footboards. Hard to call.
What made you think it was a Classic Tourer, is it written somewhere?
If just Rocket III then it looks like the closest (dependable) canned tune will be 20227 - if you wish to load it so you at least know what map you have;
20227
Rocket III
Production silencer
Full power
without catalyst
Fuel up to E10
Minimum 95 RON (89 RON/MON) fuel
But still, with the triple K&Ns too, I wouldn't be comfortable with a canned map, I would like to get AFR read on a dyno.
Unless you have another surprise, like it having a power commander with autotune!
