Just wondering if everyone else is experiencing the same drop in MPG I am getting on my 13 Tri-Glide after the stage one upgrade that included VH power duals, WH trike slip-on's, air cleaner, & SE super tuner. As I have complained about before, no one in the Houston area to dyno the bike, so all adjustments were done by the mechanic using a generic map for the 103 and his experience. I am now averaging between 26 to 29 MPG which is a substantial drop from what I was getting prior to the upgrade.
Gas Mileage Drop After Stage One Upgrade:
- Thread starter dfpk
- Start date
I have an 09 have have experienced same - curious to see what others say
No upgrade here, all stock, 34-35 MPG every tank, Happy, Happy, Happy, 
.
with the upgrade do you feel it has a lot more power ?

It is not surprising that you are using more gas. The Upgrades that you did along with the remapping allow more gas/air to flow into the motor thus producing more torque/hp.
Same result here; I'm glad to hear that I'm not alone....
I have a 2013 also, with the mods shown at the bottom. The "donor" tune they put on your trike is going to work OK, but since it's not really for your trike, the engine won't run as efficiently as it could. I had the same thing done when I did the Stage 1 and other upgrades. They put a "close as possible" download in and it ran "sorta OK" for a while. My mileage did drop until I got it dyno'd and now I'm back up to getting 33-35 (or better sometimes) miles per gallon. It took me a while to find a dyno tuner in the Colorado that knew what he was doing, but once I did, I'm happy with the way the trike runs and the mileage now.
Pretty simple, really.
There is a saying in racing: "Horsepower costs money, how fast can you afford to go?"
Substitute "gas" for "money", and you have your answer.

I have a 2013 TriGlide with a 120r crate motor (with a few mild upgrades) and get a consistent 33 to 35 mpg solo. The motor was dynoed when in my 2008 Ultra and I installed in the Trike upon purchase.
I also have a Dynojet Power Vision w/Auto Tune module that I run as a tuner. Originally the motor was Dynoed with a SEPST that was running in my Ultra. Trike runs really strong and the acceleration is intoxicating!!

i do not think your mechanic has it tuned right and you cannot do it by just guessing, it has to be dead on for you to get the results you are looking for. your bike should be getting 32 to 36 miles per gallon.
Actually...... it's not supposed to be that way at all. It's the tune that is causing your poor mileage. Sounds like someone slammed a library calibration into your ECM and patted you on the back when they took your cash.
A decent tune will not always add fuel. A proper tune adjusts the air fuel. Again, it doesn't always add. The majority actually remove Volumetric Efficiency %'s not increase them. When you reduce your VE's to match the bike you remove fuel to have a more efficient burn.
To the OP. You have the SEPro tuner. You don't need a Dyno. The SE software is free now so you can tune the trike yourself. In doing so you will set the sensor tables to match your motor and you will enjoy two things... more power and better fuel economy. It's well known that I don't appreciate the SEPro but it will tune your bike better than what you have now. Become a street tuner warrior and tune it yourself.
That's the way it really is.... ThumbUp

I have a '12 TriGlide, 255 cams, Fullsac x-pipe, Screamin' Chicken Burst air cleaner, Screamin' Chicken street performance tuner, and Screamin' Chicken Fatshotz slip-ons. Engine have 11K miles and I'm getting 28 to 31 MPG depending on my right wrist. (Stock I was getting 32 to 35 MPG.)
I have 2102 TG. Ness AC, Fullsac Xpipe, 254E cams and V&H twin ovals and the TTS tuner.
My average mileage is 37 up to 39 just riding around with a group. Most I've gotten was over 40.
Hwy at 80 MPH or above I get 27 with a head wind of about 20 MPH. Did that last weekend.

Wiz, sounds like my normal mileage (the 27) so far ;-)
You haven't been around much to work on your tune, have ya?
...and, you need to keep >>your<< wrist still.
Only done one one run of about 35 miles. Depending on weather, I hope to be able to ride more this upcoming weekend. Dongle is installed, turned on, and ready to go.
Dont forget fuel quality, total trike weight, the terrain you ride around in and how you accelerate your trike also play into your fuel mileage along with the tune. I have a 124" "mildly built" in my trike and can get from 30-34 mpg consistently on both highway and stop n go riding

Definitely has more power, sounds better and runs a lot cooler.
Do we still have wheels on that 2102 model ??? Just curious.......:cxtv: :laugh:

:Agree:
A Stage I, or for that matter, a Stage II also, when it is properly tuned will get the same, or, more likely, BETTER mpg than it did stock....IF you ride it the same.
If you are playing with the extra power, it is the wrist, not the Stage I upgrade causing the drop in the MPG.
With a proper tune, the engine will run stronger AND more efficiently, resulting in less gas needed to get the bike down the road.
One Caveat- There is a possibility (I don't believe this is the OP case) that a less than optimum exhaust system can cause a drop in MPG, even with the best tune possible.

Ya know Wiz, just to tell the difference in wind resistance & weight in relation to MPG, I have a nephew that rides a 2011 Limited w/130 engine w/254E cams. He is getting a regular 50mpg on the road. He usually runs 75-85 MPH. But I think he is still running the 32 tooth drive.
On our Trikes the faster we go the bigger parachute we become.
He just got it back out of the shop. Had a broken rear piston. It started blowing oil out the air cleaner, & had a slight rattle in the engine. It seemed to run ok.
The break finally ended up going into the ring lands when the oil started blowing.

V&H power duals, Rush Big Louie slip on's, V&H fuel Pak, Big sucker air, two people not light people, and average 32-36 mpg. Before stage one, I was at 33 mpg, but was still breaking in only had 1,000 miles.
I always use Ethanol Free fuel premium, and fuel will make the difference. I have seen as low as 29, but that was some bad fuel for HD motor, even smelled like it had race fuel mix. Next tank I was back up to 30's.

I was getting 33-34 miles per gallon in about 1000 miles. I did stage one, Vansen Hines power tools and twins/oval slipons and se air flow. 3000 miles, I am getting 34 to 35 miles per gallon.
What did you tune it with? or did the dealer just download the Stage 1 flash from HD?
Amen Wiz! Since you tuned my 110 with TTS, I picked up 2 to3 MPG with 30% more power. Now getting around 39MPG riding two up and 37MPG pulling a trailer on a 110 engine.
Fantastic!
Just finished the first tank with the newest upgrades. Stage 1 AN Air Cleaner & Freedom Performance True Duals with Racing Mufflers. TTS Master Tune Down Load. Gas mileage is 38 MPG two up mixed highway, back roads and mountains around Virgina City NV. :wave4:Seriously a TTS tune of a stage 1 should be getting 35-40 MPG especially with a couple VE Runs
PS pulls a nice wheelie........with the new 480 spring & Stage 1

Same results less mpg with the same upgrade
Just did about the same with V&H Double Slash,V&H Power Duals,V&H VO2 Breather and did SE Super with Dyno. No read on gas yet but HP 86 and T 104 on the dyno print. 2012 Triglide. Numbers almost to good to be true but sounds good and runs much stronger! The dyno was about 2 hr driving.
Let you know after 1st tank used.
On my 11 T/G;
Stage one, Rush true duels [cat out] Stock mufflers with the left one drilled out 35/36 mpg's
.But I didn't like the sound so took the stock mufflers off and added Rush slip-on's with the 1.75 baffles. With that' the mpg's dropped off with a loss of bottom end power, And a lot of noise.....
I was about to go back to the stock muffles, Then I tried DK's Thunder Torque inserts [258w]
Love the sound now and got back the bottom end ++ and also mpg's went up to 38/40...

2009 and 2011 Tri-Glides, both with dealer done Stage 1 upgrades done at delivery. No tuner, just factory download. Both trikes getting consistently 33 to 36mph. Wife gets better mileage, but she is 100# lighter and rides a bit more sensible than I do. 40,000 miles and 20,000 miles on the trikes.
