PC3 would be fine, just have it set up on a dyno. My Navigator which uses the previous generation Suzuki TL 1000 engine was an absolute pig to ride with massive flatspots, surging and hesitation. I've fitted a TRE, K&N modified airbox, full 50mm exhaust system and silencers. Fitted a PC2 and had a custom map on a dyno. Transformed the bike, the maps available from Dynojet will improve matters, but to achieve the full benefit of a Power Commander a dyno session is needed.
