Now dose a Stage 3 MT-01 Dyno Test exist or the numbers of the inceased power output from the upgrage. Looking at doing it to my MT. Any help on the subject would be great

Stage 3 tune, is more a term related to carb'ed bikes. To tune an MT-01, i guess the tuner would fit a power commander. This is where the dyno bit comes in, with the bike on the dyno the fuelling map could be adjusted for more power etc very accurately.

i'm guessing an MT-01 has opportunities for significant power increases from standard when set up on a dyno.
