What type of baffles do those pipes have? You need some back pressure for the street. Maybe install some lollipops (bolt w/washer) in the pipe ends to get pack pressure.
Find another shop also.
When I had mine done a few years ago, it was on the dyno for about hour & 1/2 and they only charged me for an hour. My bike is carbed and from what I've been told it usually takes longer to tune FI bikes than carbs but they don't get their hands full of gas from changing jets.
My 88" w/AN Big Sucker, Yost Power tube, Cycle Shack slip-ons makes 69 hp and 77 tq.

Yea, the numbers don't really bother me as much as the excessive popping/backfiring with the multi fit SE round backing plate. I "assumed" that the dyno tuning would have smoothed that out...what bothers me is the fact I was charged for 2.6 hrs when the actual time in the dyno booth was not more than one hour and the bike is popping (imo) excessively.
I'm not much of a wrench turner, but I still think there might be an air leak in the multi fit gasket/backing plate (which I mentioned at the dealer), since I didn't have all that popping going on with the other SE backing plate thats designed for the '08-'09 Dyna.
I spent over $700.00 at this dealer for the Zippers filter, SERT and dyno tuning and imo, the popping/backfiring shouldn't be happening.....
Rant over.................

I talked to the service mngr at length with the popping/backfiring issues as well as being overcharged for an hour and a half. The bikes going back in tomorrow morning to be checked out...hopefully it will all be resolved.

I had a build tuned there in the past...very knowledgable guy & a great tuner! Found a real good one closer to me though, the 3-4 hour drive to HP Express trailoring the bike sucked (too far to ride an untuned build)!

This is exactly what I am talking abot, sure your numbers are impressive, BUT YOU ARE BEING UPED by your tuner, these numbers are in STD MOD, not applicalble in the United States, these are European umbers, take away about 3% to get to the U.S. unit of measure, your at about 99 H.P. Look at the right side of your sheet, where it says STD horsepower, that should be SAE horsepower. Not to mention that your timing is way off, those lines you have are NOWHERE near smooth, they are wavy as hell, I would NEVER let a bike out of my shop with lines that looked like that, it makes me wonder if they even tuned it with air fuel or just threw a canned map in it and guve you a dyno run. No offense, your bike is by far impressive, but with a proper tune, it has the potential to be so much more.
