that is not much to look forward to. my 2010 LTD has 65.7 HP and 76.5 tq.. these things are really choked down. there are a lot of 96" bikes that are making more than these new 103".. the thing is the bike runs well now, feels a lot stronger than what the dyno says.the dyno i used is not a happy dyno but still seems pretty weak # wise for a 103". matter of fact my brother has an 08 ultra 96" just a set of mufflers, decent aircleaner,and a tune using a PC V. made 79hp and 93 tq. now if that is all my bike could increase i am short a bit of a 96" pretty sorry i have to say..
Think of it this way, if ALL conditions were equal, you would think the 103 would pull a couple more HP and TQ than the 96, just makes sense, right?
My LTD has better numbers than yours, stock...............BUT..............this was on a dyno in AZ. If YOURS was on the same dyno, same day, same conditions, I'll bet we'd be pretty close to the same #'s. Remember, all bikes are a little different. Mileage makes a difference, as does oil temp, tolerances when assembled, etc. etc. To say a pretty much stock '08 96" makes those #'s I would say, yes, "Happy Dyno".
I'm at the point now, that my '10 runs pretty decent and I am happy with the tune I have. Heat has been manageable, power delivery is very smooth, I guess what I'm trying to say is that my bike now suits ME. I don't really care about the numbers, as long as I can out-pull the stock bikes in our club!! LOL
Just like the sound of your mufflers.......it's all pretty subjective, right??
Just my observations, as usual! LOL
