i have Ti Leo's... i contacted Leo Vince and they have recommended using a map for any other slipons. They recommended NOT to use euro maps on US/Canada bike...
i've tried the graves map, i think i ended up using it with the 'butt-plugs', but it was far from ideal.
you'd think that the baffles do not restrict much... try taking them out, load -03 map, put in earplugs and go for a ride. yes the noise is... well... it's loud, but i doubt you'll ever want to put them back in. The bike runs soooo much better, lot faster, lots more top power...
now maybe the -02 and -04 maps are just crap, and with good map baffled bike would still run great. maybe. or it might be that the baffles really do make a significant difference - i'm sure the -03 map could be improved as well...
Only way to know for sure is to have the bike dyno-tuned both with and without the plugs...
i will be eventually getting a custom map for baffles-in setup, as the local track is quite anal about the noise restrictions, but because of lack of qualified tuners in the area, i did not get it done this year... hopefully in the spring, a new dyno-centre is opening not too far away...
once i do get one, i will post it here, i'm sure for most people with slip-ons and standard SD it will work better then the dynojet maps.
