Now the interesting part:
Green: All the mods no map
Red: Mapped with PCV revlimiter +500rpm
The greatest gain was given by the removal of the air filter cover, the big difference from 3500 to 6500 rpm.
The cat removal gain, said by the Dynojet technician, was almost nothing and for the Akra too.
So a better sound and less weight only.
Without Power Commander the bike runs lean but will not cause damage. Pirate racing video was right.
So the most effective mod cost nothing but if you care about the bike with the PCV you have +3hp and the right air/fuel ratio.
The PCV was from an Husqvarna 701SM but it was necessary to invert the wires of the injector connectors.
So be careful.
The modification was from a Dynojet reserch center so I think the right PCV for the Vitpilen will be ready soon.
Now the only problem that it’s raining… I made few kilometers yesterday and the bike is very punching in the mid revs and it runs very smooth. Will see with more kilometers.
