| To make the best of what you have engine wise make sure all the standard stuff is set up perfectly. e.g. throttle postion sensor, cams etc. A few hundred pounds spent on making sure everything is set as it should be can make a big difference to the throttle response and a few BHP.
A power commander can help with fueling and the latest ones can be mapped for both front rear cylinders separately.
Maybe Junk the air intake mesh, fit pipercross in tube filters (and the air box restrictors if fitted?)
Thats probably as far as you can go without starting to spend a four figure sum.
The FIM ecu is good but more expensive, yer makes yer choice and pays yer money. There are a good few specialists on here who would probably be able to help you achieve what you are aiming for.
