Disappointing Stage IV Dyno Results: 2015 Limited
#21
BigEd04 - much appreciated. I emailed Dave last night and he called me first thing this morning. He seems top-shelf and I have forwarded the dyno sheet to him for suggestions. My question now is whether I should even ride it. Really sucks as I "was" scheduled to ride to Sioux Narrows Ontario next week....

Something else I noticed about your dyno sheet. Torque and Horsepower should cross at 5250 rpm's. Yours looks to be a bit to the right according to the graph, 5400 to 5600. Could be the scaling? Maybe software is not calibrated correctly don't know. What impact it has on your tune, if any cant say, but it certainly cant be good. A good tuner is worth his weight In gold. Their are some that work at Dealerships, very few, and the dealer isn't going to give them the time it takes to correctly tune a bike. Usually start to finish is a minimum of 3 hrs, can be longer. If some one says they can tune a bike for you in a couple of hrs what they are doing is downloading a base map and running it on a dyno. Not really a tune. Base maps are a starting point to get the bike in the ball park so you can properly tune it. Once you get a proper dyno tune you will have a smile on your face!!! Good Luck.

Disappointing Stage IV Dyno Results: 2015 Limited
Wow, those numbers are terrible, man. Definitely take it somewhere else! I did an S&S build in my 103, just cams, duals and and intake, my tuner (Dan Thayer, holds the patent on the Thayer 3 stage oil pump) got me 100 hp and 107 tq with my power vision.

Maybe the tuner shoved a sock in the tbody, these numbers seem impossible to be honest. Even the base run before the tune would give peak numbers better than that. There's enough proof on this forum of this kit under performing but this one takes the cake. Retune I guess, 2 hrs is on the low side. I would want my cheddar back. Stage 1's blow this away, that would be my money back argument. Good luck.

Thanks for all the input. I am scheduled to leave the bike with a different tuner. Yesterday I spent 2 hours at the dealership that built the bike and no one was happy when I left. Now the dealership is trying to hold the warranty card over my head by saying "We could get HD involved but then your bike will be flagged due to the Stage IV kit, and warranty items will always be an issue." They also continued to say that I chose the Rinehart True Duals and this is the problem. Their position is that they have done several other wet heads with a Stage IV kit that make 115 HP and 115 ft-lb, but they all have different pipes. To them this suggests a pipe cause; to me it suggests a lack of tuning competency to deal with the pipe interaction or there is something fundamentally wrong with my build.
Man, I am so disappointed and pissed about the time, energy, and money.

Hang in there.....you will get it worked out. Went through the same thing with a dealer tune in 2010. Although my CVO Ultra isn't a wet head, its a 2010, it made 105/123 on the dyno with stock SE255 cams, stock pistons. The heads worked by TMan, and it was tuned and assembled by Doc's Performance in Fl. Oh and I forgot......I am running Rinehart True Duals system. So it can be done.
