Dyno runs aren't cheap...if bike's running fine then leave it be.

The SEPST calibrations are pretty good. But if you want to get the most out of your bike's performance a dyno tune is the way to go. That is, providing the tuner knows his stuff.

I'm a convert to dyno tuning and I suspect you will find a worthwhile benefit if you get yours done. It will be a miracle if your current tune is even close to perfect!

Actually, that same kit (92500003) was installed in my 103 SG by the original owner at 200 miles and includes the 254E cams ... with the cam change it definitely needs a dyno tune to get the benefits of the kit. The curves I got with the bike had a best of 83rwhp/94rwt with only the 200 miles.

Since I purchased the bike at 1,500 miles, I added the Heavy Breather and went with an FM 107 kit. With the only changes being another 1300 miles and adding the HB, the initial dyno run before building the motor was 87rwhp/103rwt.
