PCIII, Dyno And bad Mileage.........
Back in july i had the AN big sucker and PCII put on and the bike dyno tuned. Well my fuel mileage went to hell in a handbasket. Like from 40-42 2-up hiway and 38 or so in the city, to 32-33 2-up highway and 29-30 city. I phave put a few hundred miles on it hinking it will get better but nope.
I totally expected to loose 2-3 mpg but not 9-10. The Indy i took it to says that something is wrong and he will put it back on the dyno but he WILL charge me to find out whats wrong and fix it. I am frustrated with this shop and NOT taking it back to them. SOoooo, now the question is do I take it to a different shop or do i try to set it myself???
I will be the first to admit that i know nothing about how to set the PCIII up but i think I could figure it out, I havent even looked at the book yet.
Soooooo, what would YOU do??????

Here's what I would do:
Get rid of the dual exhaust in favor of a 2:1 - either a V & H Pro Pipe or D & D Fat Cat.
Return or sell (throw away?) the PCIII. Call Zipper's Performance (www.zippersperformance.com) & get their ThunderMax EFI System with Autotune. You'll never need to dyno your bike again (to tune it anyway).
That's where I'd START. Save some cash & get a BIG BORE (NO, not a 95 or 103 either) kit that WORKS. More power with decent fuel mileage is always a GOOD thing.

I agree the 2-1 is a better option for performance over a 2-2 set of pipes. I personally went with Thunderheaders myself.
As far as problems with the PCIII, I don't think that's the issue. I put the PC on my bike when I got the pipes (already had the SE air cleaner on it). I just downloaded the default map for my configuration and left it like that. I could tell it performed better, and the gas mileage dropped maybe 1-2mpg all around.
I would try it that way, start from scratch and the basic download. It's not hard to do, just attach a computer (with the latest map) and load it. If you have a laptop you can leave the PC on the bike, or detach it and (with a 9v battery attached), connect it to your desktop computer. Start with the basic configuration and see how it runs from there (there is a possibility that it's already at that, but if the original shop tuned it, I'm sure there's something different.)
I installed the whole thing myself, and I'm a mechanical idiot, so you should have no problems. If the default map doesn't help, then you might want to go to a shop - maybe a new one, and see if they can help any.

bad milage
guess if you know the very minimum about the pc-3 you can adjust it yourself
meaning in your normal cruise range 2-4 grand subtract some of the values
or if you check with some of the folks here on the forum there are a few that know these things as good if not better than some tuners .

i would find someone who has a similar setup to yours. get a copy of their map, or get a map from the pc site that fits your setup. save your map, and then replace it with the new map.
you can also do a search for user 'iclick'. he has done a ton of experimenting and tweaking with his pcIII map to get optimum performance/mileage.
