Au contrair mon ami.. the Mighty Scura was out in SoCal for years without a tuneup and ran "fine." When I brought it home, I checked the TPS, and it was some crazy number like 340. (!) It runs beautifully, now.. the little hesitation it used to have at about 2400 at very light throttle is gone. When checking it when trouble shooting during "the incident" at the Spine Raid, it was 145. Still runs fine, haven't made time to reset it.
