The purpose of HAVING a PC in the first place is to facilitate tuning. Honda installed a perfectly good map on the F4i, one with smooth, manageable power, with some concessions to lowering emissions at below 6000 RPM. A PC wont make the bike more powerful without intake/exhaust mods. After the mods, a tune will identify peaks and troughs in the power curves and fix them: downloading someone else's map assumes his bike acts the same as yours, and you like the same power curves.

RE: Dyno
I dont have any problem with a PC, I've used them on two of my bikes. First generation FJR owners claimed the bikes ran much cooler with the PC and a richer mixture. I just have a couple of issues, how do you know if you are better off without getting it tuned, and at least in Cali, bikes are supposedly going to need smogging soon, and the only streetlegal PC is the EX model, which is not tunable at all below 6000rpm.
I just dont see it as a "must have" mod unless you actually pay for a tune too. I saw before and after maps, and the downloaded maps were certainly not smooth, not even as good as the stock map.

I also disagree,the stock map is made for emissions not straight up power..But a pc and a good tune will make the bike feel WAY better..
Hell with a tune and a pc ,mine got BETTER gas mileage and is smooth as butter.
Having went from a stock bike ,to a pipe,then a few months later a air filter,then a pc (with a dl tune) then finally a dyno tune.No compairson between stock and now.
A pc is worth having even if the bike is STOCK..
Bikes just like tahoe said are geared towards emissions,and the worst possible rider in the worst conditions and not have any problems.Just like on a f250 6.0 turbo diesel ,put a good tune on it and pick up a easy 75+rwhp and 100rwtq..Mainly because it was tuned for the above conditions.
THe pc takes out the "extra" fuel and lean areas in the map.Makes the bike a lot better to ride.
