It won't hurt, its pretty easy. Seems like an awful lot of money to lay down to slightly richen your bike in the higher RPM ranges. I say richen because most, if not all, Warriors are somewhat lean when built. You might gain a little HP/ft-lb and mileage, but other than that..... Basically, the benefits gained from the PCIII are directly proportional to the performance mods you do. No mods = not a lot of gain 4 da $$$ IMHO...
I ran my PCIII on my stock bike for a few weeks to test it out while I waited for my exhaust to arrive. It did make a noticable difference in off-idle and mid-range "smoothness". If you arent planning any mods. Dont waste your hard earned money. Send me the $300 bucks and I'll tell you how to adjust your ECU.
OR, you can go to Redhorse or Washingtonwarriors websites and get it for free. I take paypal too.
If you plan to replace the pipe or do air mods anyway in the future, keep your eye out for a good deal on a PC-III and put it on even if you are 100% stock at this point. I picked one up for $200, definitely richened up the top end and the bike pulled with noticeably more power. I'd say go for it. Use the M403-001 map.
