2015 CVO Road Glide Ultra - Fullsac DX and V&H Monster Ovals with the Harley SESPT.

Quick story, I rode the bike out to the tuner's shop. He had his guys immediately take off the stock pipe and install the DX pipe the X&H slip-ons, he had insisted on using the SESPT and told me how thrilled I would be over the stock setup. Bottom line is he never did a baseline pull and the blue baseline you see in this graph is after the new parts are installed but before he "tuned" it, I think he put in a basic map of some sort first. He made three or four pulls, each time improving it slightly but the end result is what you see. The numbers basically line up with everyone else's stock numbers I've seen posted for a 110 everywhere, even a tad worse... and that's exactly how the bike feels to me. The power feels stock at best and to be honest it seems like I spent a bunch of money to make noise and if the F/A mixture is now richer as would indicate, I'm using more fuel to make the same numbers. Obviously I'm not happy with the results. He kept blaming it on the V&H Monster Ovals which I have hard time believing would cause this poor of a showing.

Comments and personal insults welcome. Keep in mind the blue run is NOT stock, but after he put the parts on.



My intention at this point is to ride it out to Fullsac and have him tune it with a TTS and add the 2.0 power cores.

I believe you're correct about not getting your money's worth.
I'm not sure what numbers you're assuming you'll get having changed *only* the exhaust. Low to mid eighties sounds about right... But the torque seems low.
A tuner who didn't do a baseline before he installed his parts is shady in my opinion.
I'm betting you rolled in there with 80/100

Pretty much every dyno sheet I see for a CVO 110 with a header, mufflers, and a tune is around (or even a little north of) 95/105, which seems to be supported by the good folks here. Keep in mind I'm not just spouting number, I'm going by seat of the pants feel, before/after. It just doesn't feel improved. All the stock dyno sheets I see for this motor pretty much agree that 85/102 is the baseline.

Also please note the time on the runs, first pull 10:54, last one at 12:10 so only 1:15 on the dyno and in that time he took some calls etc... Seems pretty lean on the time investment no?

How much did you pay for the Dyno? No stock pull. Most runs I have seen take 6/8 pulls & 3/4 hrs. But you gotta have a real start point, which he never did.

250 + 150 to install the pipes.

Not sure why he didn't pull a baseline run with the OEM parts. Looks like he was trying to show you his tuning abilities with the SESPT, rather than proving the results with the aftermarket parts. Sad. A note though--when I sent my dealer the list of parts I wanted on my bike, he recommended against the V&H Monster Ovals (my original choice). Recommended 4" Rineharts instead; he said the V&H pipes were bad for low-end torque.

In fairness, he did mention he didn't like the Monster Ovals.

How did you go about finding and deciding to use this "tuner"?  What I see there is something similar to what you get at a Harley dealership, a canned map and very little time actually tuning the bike.  A good and thorough tune is more likely to take 4 hours or more, not 1 hour. 

I have to believe if you take it to Steve at Fullsac or Steve at GMR, you will see and feel a big difference.

I have had pipes and tuners done on all my bikes and was never that thrilled with the power gains. It takes compression and cams to get real noticeable power improvements. I ended up with 87/104 with the DX pipe and 1.75 cores tuned with a TTS.

Mapping a bike for $250.00 will eventually have you on welfare, and signing up for food stamps. Furthermore it CAN'T be properly mapped, both cylinders, in an hours time.

I'm thinking that pipes *alone* should generate 85-ish and 100 tq.
If anyone is hitting 95hp with ONLY a pipe, I want one o' those pipes.


I'll have to find the old sheet but my ultra (2010CUSE) did like 86/100 with a SEPST and Rinehart TDs.
Maybe the '15s are a little stronger.(?)

Regardless the accuracy of expectations, you simply did not get a proper tune and the lack of baseline tells us the guy KNEW he sucked and didn't want to be exposed.

Lance,
You saw this chart earlier, but I thought I'd throw this out there.  My butt dyno says these numbers are probably for real.  The head mechanic at LRHD has many years in the business and admitted to being a little disappointed in the numbers, and had hoped for closer to 110 torque.
It's still the best running bike I've ever owned.  No complaints here, and vastly different than stock IMO.
This chart is my '15 RGU with stock SE breather, a SEPST, V&H Monster Rounds and Pro Pipes.

Harry, yeah I was expecting something like those numbers. Your numbers aren't isolated and are right in line with what everyone else has said with a good set of pipes and a good dyno tune. I hope I'm not breaking any rules here, mods please edit if so... but here's a thread on another site where everyone posts stage one 110 numbers vs. stock and stock looks right around 85/100 and the "after" is generally 5-10 points higher on both ends. http://www.hdforums.com/forum/screamin-eagle-cvo-models/721825-whats-your-110-dyno-numbers.html My numbers are worse than every other example in that link...

I went out and rode the bike today and aside from the official numbers, I don't feel it on the "butt dyno" like Harry said. In fact throttle roll on in 3rd gear or higher from 2500 RPM is really "farty" and the bike doesn't start to respond like it should until 3500. The bike stock was really torque-y at lower RPM's and it was one of the things that put a smile on my face when I bought it, a 6th gear roll on even as low as 2200 RPMs was smooth and powerful, not now.

The red flags are there and you all spotted them like I did... But I don't want to badmouth anyone or say they suck, certainly don't want to mention names because the guy came recommended by people I know. If they're happy with his work then cool, maybe they don't know any better, or maybe my incident is an isolated one. I'll most likely just count it as a lesson learned.

I'm riding out to Lake Havasu at 4:30am.

Sounds like a good choice. I'm running the DX and 2" cores along with the SEPST and "according to my dyno sheet provided by the dealer that did the work", I'm sitting just under 99 hp and a little over 112 tq.

I have full sac pipes, V and H 450 and the SEPT.

Before he started the tune I asked him what were the ball park numbers i could get.  He said i'm not promising anything but you should get at least mid 90's and around 105 or so on torque, but we'll see.

I was the only tune on the schedule for the day. In fact the day before he told me he would tune it at 9:30 the next morning and so I showed up at 9, my bike was there over night.  The tuner is the same tech who tuned my '14 which pulled hard, and ran great.  I was hopping for as good as a result on this bike.  This guy takes his time, he is methodical and deliberate and I watched thru the window just like with the other bike.  They also have remote monitors above the glass.

On the 4th pull he had 98 HP and 110 lbs of torque, I was very pleased/stoked and I gave him a thumbs up thru the glass.  He looked at me, smiled and put his thumb and first finger apart, like, i can get a little more, I gave him another thumbs up.

I'll post the sheet tomorrow, i'll have to take a picture of etc.

My numbers were 100. something HP and 114. something lbs of torque.

East coast has some humidity, but that early in the morning the temps and humidity were pretty good so the conditions for this time of year were good for a tune.

The Bike pulls hard, runs good.

We have similar pipes, Ful Sac and V and H 450 slip ons, so I think it was the tuner,because there shouldn't be that much of a difference.
