I just had Rinehart True Duals put on a few weeks ago and had it in for the 1000 mile maintenance as well as tuned/dyno'd. I bought the street tuner through my dealer. I picked it up today and I am still getting the backfiring on deceleration. My paperwork shows it at 81hp / 103 ft torque.

For some reason I was expecting more out of it. As well as the backfiring eliminated after the tune.

Any thoughts?

Thanks!

Sorry, that was 108 Ft. Torque

With V&H true duals and V&H Hi Output mufflers my dyno was 89 up and 108 tq. According to this site the hi ouputs are supposed to kill the numbers. Who cares really. Are you a number chaser or a rider who likes a bike that sounds right?

Depending on the level of popping your numbers are about norm. Take all the highs and lows out of the numbers you'll see here and your in the range.

My brothers 103 that's got pistons, heads, cams and your pipes run real nice. No popping. My guess is the shop slapped in one of their canned tunes and said here you go. Good tuners start there and dial it in on the dyno.

I'm more concerned about how it sounds and performs, not the numbers themselves. In saying that, I agree and do not think it was tuned properly. If it was, I would not have the backfiring issue. It seems to run fine, but I only rode it from the shop to home so far.

If you actually bought the Street Tuner, rather than the Super Tuner, then you didn't get a full dyno tune, you got a street legal map that was designed for a street legal Harley exhaust system.  You might want to start by verifying exactly which product you bought.

Yes, it is the street tuner. I guess then that is the best I am going to get out of it?

I would be fine with it if the popping on deceleration was gone......

In my (limited) experience, a bad tune will be very evident on the low end. Test your bike in 1st-3rd gears; if the ride isn't smooth then you might want to look at getting a custom tune.
I had a canned map on my first bike; it was choppy, had lots of popping, struggled on the low end, but was on fire a higher rpms. I didn't think the high end performance was worth the rough performance in everyday riding. When I changed the exhaust and AC on my current bike, I made sure I had a proper tune to go with it. Runs amazing, sounds solid, and pulled 96 hp (if you're into that sort of thing.)
