From the DP kits and open airbox mods and what not I think the best place to start from would be a PCIII. Now there aren't too many dynos in Ireland and even fewer skilled operators so I'd probably be relying on the expertise of the wider community. As mentioned I have a 2002 ST4s that has Remus aluminium cans that are stamped not for road use. The previous owner has told me that a Ducati shop set the bike up for these cans. If anyone has something similar and a PCIII with a suitable map, I'd love to hear from you. I was going to go to Ferraci to get the PCIII as they might have a suitable map they could preload too. The onloy problem is import duty, which is a pain. It runs at about 20%. So, any wisdom, anecdotes, or just wild encouragement people might want to share, go right ahead.,I am running a PC3 with Open Airbox , K&N Filter , Sil Cans and Iridium plugs and I am having to run with a map supplied by another owner with a similar set-up however it does have some peculiar and inconsistent fueling issues which I need to overcome with a proper dyno-run. (E.G. Higher Fuel Co-sump at 80 mph than 100 mph) I would recommend that you investigate the nearest PC3 Dyno technician (I appreciate this may not be convenient , Its the same here in the NE of Scotland) and have it mapped correctly which it really should have anyway even if it came with a map from Ferracci as each engine is different in its requirements. This is something I will be having done this winter as I would not want to run long-term without knowing the fueling was correct for many reasons apart from fuel co-sump. When I get the work done I will post the results but it wont be for a few months yet. From a different angle , have you already changed your sprocket set-up ? Quickest to try is a 14 T Engine Sprocket which doesn't require a longeer chain , a better arrangement is to keep the OEM 15T and increase the rear from its OEM 38 to at least 41 (I have 43T but find it a little to short geared so will try the 41 next time out). This tends to address the lumpy low speed riding for most people.,,,
