No I don't have any idea about where a good place to take it might be, spare one name that always seems to pop up when I start talking performance. The guys name is Al and he runs a place called Hypertech engines. He is a real straight up kind of guy, and wont hesitate to tell you whats what, even if you don't want to hear it. I have not, however, used him for anything. I was trying to rebuild an 89 FLHTC once so I called him. He wouldn't take the job on till fall, and I wanted to ride so I convinced Heritage Harley to rebuild it. They did a good job, BTW. If you go there request that Kendal work on your bike, he is a good character also.
Good Luck
