Here it goes, what I've done so far engine wise:
O2 sensor eliminators, disconnect 2nd-3rd gear restrictor, Mivv cans, remove secondary butterflies, SAS removed, butterflies balanced, custom home made airbox-filter.(get one from motohooligan in parts section)PCIII with custom map.
Sadly the best results are from O2 sensors and custom map, this means you have to get a PCIII or tuneboy and sort the exhaust also, which means $$$
On a positive note I probably save the costs back in a year on petrol and it's sooo smooth on the trottle. HP from 109 up to 113. (very conservative dyno I have been told... )
Ahhh and forgot one tooth down on the front sprocket...
