First Dyno Tune
« on: May 13, 2006, 06:31:41 AM »
My first dyno tune. I am so excited and yet easily amused. After losing the son of a girlfriend's shop to the poor economy (or poor business practices) I ended up at a referral from Van Nuys Harley Davidison, in CA. The "service" rep gave me some bad advice, didn't tune the bike with a dyno, and dispensed experienced remarks like "you should wait until you have about 10,000 miles before taking it to this place...". It's install and guess at a map setting and off ya go at this dealer.  
 
I ended up at a place where every guy in the shop is a wrench; trained and experienced in HD performance parts and installation. It was a fluke that I found them; the guy who referred me is the same service rep with the questionable advice. Go figure.
 
Anyway, I hope I can post the results properly. After the first baseline results, the tech at the new place who specializes in dyno tuning, pulled like 10 more horsepower and 12 + ft lbs. of torque with some tweaking in 15 minutes.  
 
Next stop for the mod path is a 50MM Screamin' Eagle Throttle Body and a close loop computer module from Mentor. My ride is destined for 25-30 more horsepower in the next few months. Unless there is some other opinion about the upgrades I have chosen? I am listening and reading your input.
 
Oh, my ride is just beginning to open up a little. The power band seems broader, but the real test will be Saturday morning when I take it out for a real spin. I'll keep ya all informed on progress.

Very nice numbers Kona.  I've installed the 50mm tb and cnc heads and can tell you it makes a big difference when matched up to the right airfilter and exhaust.

You have an '06, right? Which 50mm Throttle body did you use? Screamin' Eagle? How did you decide on the 50mm instead of going larger with heads?

Were you able to mount the S.E. 50mm T.B. up to the stock CVO heads?

I used the SE 50mm TB and SE CNC heads and 10.5:1 pistons, and a few dozen other upgrades...
