I bought the PC3 USB to use the dynojet shifter. I have the stock map in the unit, will this stock map make much of a difference in HP? will it help to take it to a dyno and get it tunded for MY bike? Just wondering, if the gain would only amount to 1 or 2 HP for my stock bike I don't think it'd be worth the trip to the dyno.

Any input?

With the PC, its not so much the HP you should be lookin for but improved power delivery and as close to perfect A/F you can get.
If you haven`t got a can yet it proberly is a waste of money because you will only need to tune it again when you put a can on it.
Prior to me tuning my bike it was very jerky down low.
When I had it dyno tuned I did get considerable HP gains but even more importantly for me the power delivery is very smooth from as low as 1500RPM and A/F is just about spot on.

get some more upgrades first then go. like air filter and exhaust and then you'll appreciate it more.
