1 yes youll fry them otherwise and it will dial out your upmpap if you leave them wired and in.
2 i cant say for sure because ive never seen the data on their files. Im happy with my tune from them.
3 thats a personal choice. Arctic and i differ on opinion. I dont want an open loop only bike for road use for reasons ive said Without data showing me it can adjust the way i want it to. If you dont travel far, have consistent gas, trust the person building your map is competent it Should be fine. Worst case from what ive seen personally, it may just run rich at cruise. Arctic and i have differing opinions on this. I agree 100% with arctic that a custom tune beats a canned one.
