Hi was wondering if i can get some input i just bought a 2011 street glide the guy just had done the Screamin’ Eagle® Pro Stage II Kit part 92500003 and screaming eagle air cleaner and rinehart 2 into 1 pipe IT come with a super turner and he did not get it dyno,d so i assume they put a generic stage 2 flash on the bike.Anyways the bike seems the run good pulls really nice is it really necessary to get it dyno,d or will i be ok the way it is?thx

 

A good dyno guy can make it right but if ya are happy with how it runs, no.

 

If your happy. And the spark plugs look good, then your good to go.

 

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.
