What Dyno Results Can Be Expected
I am having the bike Dyno Tuned Friday. Was hoping to get best guesses on what numbers i could expect so that i know whether to be satisfied that the tuning specialist has done the job for me or not. On the other hand i don't want unreal expectations and look foolish either.
Bike is 2010 SE Street Glide (FLHXSE), stock 110, SE heavy breather, V-H Dresser true duals (not power duals), Klockwerks Revolver Platinum Series 4" mufflers, SE Pro super Tuner.
Thanks in advance

Here is a dyno sheet that shows stock and after the tune.

Well they aren't the numbers I've seen here but I'm very satisfied. I don't have a stock base line as the mods were done before it was dyno'd; but naturally we have a base line with mods but before tuning.
At installation of the Heavy Breather/V-H true duals/Klockwerks the 110CVO-Heavy Breather-Race Exhaust map from Harley was uploaded with the SEPST. I knew it was a generic modified map, but had no idea how LEAN it was. Look at the Dyno... it hovered between 14.5 and 15.5 to 1 AFR. Cylinder Temps in the dyno room were a high of 296F front and 321F rear... using a laser heat thermometer gun. Also notice how bumpy the curves are! All of that was noticeable in the grip under hard acceleration.
After tuning temps dropped to 238 front and 259 rear. Over all a 10% increase in HP/Torque to 91.11/111.31... simply by tuning; and as you can see a considerablely smoother curve. Also torque curve starts peaking in down around 2800 - 3000 rmp rather than at 4000 rpm... far more useable I think. Decel pop is gone, throttle response is so much better...no lag or lumpiness at all...and I may be crazy but I think it sounds better too
I highly recommend a dyno tune if you do any mods. I'm a believer. For 190 bucks and 3 hours of your life, it's well worth the investment. Imagine if there was one part you could buy for $190 bucks that would give you that noticeable of an improvement... they wouldn't be able to keep them on the shelf!!
