are you wanting to do the tuning or do you want some to do it for you? We use one here in longwood area. I think it is 100 bucks for the first hour then 60 for every one after.
I'm not sure what I can tune other than the timing and a/f ratio. I'm installing a new engine and want to make sure all is good before it hits the track. The a/f is my main concern.
I'm in Jax also and haven't found anyone around here to use. I believe some of the local IT guys have used Stage 6 Motorsports for dyno tuning but I haven't personally worked with them.... http://www.stage6motorsports.com/
I was not aware of what kind of computer you had. You could be tuning a motec if you wanted to. However in yoru case any dyno will do. here is a quick list of dynos in the florida region. You can look through it and find one close to you.
