The lurchiness of the stock setup was never really an issue for me but the idle stability was. Either way, the throttle body modifications that Wade at Injectioneering did to mine were the one thing that made me decide to keep my 12. The bike now lugs down to idle and comes back up perfectly, starts easier, and virtually refuses to stall. I called him and thanked him after my first tight trail ride. Far and away better than anything else I tried. The first crack of the throttle is really easy to modulate. The tuner will not affect the bike in the rpm ranges you guys are talking about, as Gray already said. The throttle cam sounds like a bit of a band aid. I rode my buddys stock 11 the other day and the difference was apparent immediately. I used to fool with the maps on mine before the mod but now Ive just been running the stock map everywhere. Semi desert to wet, 3 ft logs. The bike now just runs like it should. They're your bikes and money guys, Im just telling you what I found.
