I just purchased my first HD ( 2010 Street Glide ) and I installed the V&H 2 into 1 Power Duals, with dual Rinehart slip On's. I also baught the Screaming Eagle Super Tuner along with the Arlen Ness Big Susker kit. My local dealer said the could not complete the full Dyno until I have at least 1,000 miles on my bike. Does anyone know if this is accurate as I have heard 500 miles was adequate? I was also wondering if anyone else has used this combo or know of anyone with combo, and would be able to tell what type of HP/Torque gains I should expect see vs. stock once it's been fully tuned on the Dyno? Any feedback would be appreciated..

 

My dealer wouldn't dyno my bike after my 103" upgrade until I put a 1,000 miles on it. Some builders will do the break in with the dyno but most dealers won't dyno it until you put some miles on... usually at least a 1,000.

 

The rings are all settled in looooooooong before 1,000 miles.
No harm in dyno tuning a new engine, if you know what your doing.

Yeah alot of places like you to have 500-1000 miles on the engine, but like was said it can be tuned before that as long as the tuner is good-meaning the guy doing the tuning LOL!

 

There are builders that will break in an engine on the dyno and just do a couple of 3500-400rpm pulls through the gears to check AFR. A true dyno tune could take as many as 30-40 pulls, many of which are WOT. I wouldn't want any of my new builds put under that load unless I had rolled up about 1000 miles. Better safe than sorry; if it goes up in smoke, the tuner is not responsible.
