Loss of power update
A few weeks ago I had an Indy put cam bearings, cam chain tensioners and lifters in my 01 EGC. I picked it up and it had a very noticable loss of power. Once he got back from vacation I took it back to him to go back through it and put new tires on it. I mentioned it had gone from 40 mpg to 30 mpg. He did a compression check and a fuel pressure check (both good) and started into the engine while I was there.
Picked it up the second time, he found nothing wrong in the engine but noticed it had running rich. He mentioned I could down load a new map for the Power Commander. My buddy was following me home in my car and said he could smell rich exhaust inside the car.
A $1000 later I have a reliable bike with new tires that runs like crap.
I'm strongly considering taking it back to the Indy that the previous owner used (about 70 miles away) to intially installed the exhaust, A/F and Power Commander and have him retune the bike.
Here's the question. Is it somewhat normal for power commanders or other tuners to periodically loose their map and have to be retuned?
I tried the disconnect the battery trick I read on here somewhere and no change.

Are there any rally's ever close to you?
Many dyno-ers do the rally's and you can catch them there..
How far is the closest dyno-er to you and what do they tune with?
I live in a small city area, less than 100 K population
and they're are 2 dyno-ers w/in 40 miles of me.
If this is completely out of consideration then the only thing you can do is try and find someone on this site who is using something close to what you are running or go to the Dynojet site and see what is close to yours..
Are you running a PC-III or a PC-V?
