Tuning on the cheap..

if your pc3 is mapped for no flies and you got smaller ones in then that's gonna be why the performance has dipped I reckon mate

yeah, possibly. I've played with quite a few maps on this bike, and got some odd results.  Mine is running mivv can, trimmed flies, Lars airbox, BMC filter.
The map is supposed to be for a bike with removed flies, and decat too. This map is the best its ever run, even better than in standard tune! You'll have to play with some of the maps from the zipfile I put up here before. Gotta be better than spending a small fortune on r/r tuning and custom mapping.

Deffo. Weirdly, it's so much better on fuel tuned than it was stock. Shows how restricted they are to comply with all the euro emissions crap

Yep, I found that too. I got 48mpg out of it tuned up once. About 40-42mpg average quick riding. It dipped below 40 without tuning.
