I think you should put it off indefinitely. Penner’s unrestricted tune increases the rwhp to over 170. In the face of that. enhancement by any filter will be unnoticeable. I’ve heard that the new plenum is more efficient than the old but I’d bet that ripping that plumbing out and putting filters on the throttle bodies would have a significant effect, along with decat-ing and retuning.
hey Dougl, how long it takes to learn as much as you know about motorcycles? you seem to have tons of knowledge about engines and motorcycles.
 
Hello everybody, Is it possible to make power wheeling with the rocket tune with the penner's map? Thank's ✌️
