A PC5 with the downloaded map will help a little but it will run rich. I would wait to do a dyno tune until you're done modifying anything intake, engine, exhaust, and ecu. A good dyno tune should gain you around 3-5hp peak and some low end power with just a slip on.
Get yourself a PC-V
; and then a BMC
air filter; get the slip on & a link-pipe; this is also the time to shit-can the EVSM & all the cable crap under the seat, and the myriad of hoses and charcoal container, etc; also think about getting some plate (there are lots of options) on the cam cover, thus doing away with the PAIR (Kawi's verson is called KLEEN); now send you CPU out and have it reflashed - the best bargain going around is Schnitz Racing
of a base price of $75.00, add these two options: disable EVSM & PAIR@$10.00 ea., so for about $100.00 you get the whole enchilada. The nice thing is if you ship it out SAT-TUE, they'll probably have it back to you by FRI or SAT.
Now this might take you up to a year or two, depending on finances & time. That' OK. During this time talk to other riders in your area about who has the Wizard of the Dyno
. If you're having a hard time finding sportbike riders in your area, go to a weekend of racing. Most riders will be more than happy is revealing the name of their Dyno Ace.
After, and only after you have the sundry items purchased and installed, now you book some time for the Dyno Magician
, taking it to a dyno equipped shop. Depending on weather conditions in your area they may need it for a day or two, or even for a week+. It's all worth it end the end, you'll be really glad you did.
