88hp is the stock output at the wheel. The Honda claimed 106hp is just the engine numbers on a bench dyno, no drivetrain loss. As far as why they started that low with the add-ons, you probably guessed right. The previous owner has taken the time to swap out to a 1300 final drive to lower the cruising RPMs for better gas mileage so it is a good bet he had the PC3 tuned for best MPGs not power. Unless you are racing, there's really no need for max power. As far as the accelerator pump feature, leave it off. It just wastes fuel and as the VTX runs rich at the mid and upper ranges, it's just dumping more fuel where there is too much already.
06 Vtx1800R/S hp/tq numbers low
I am going to list my mods related to performance right off the bat so that anyone who doesn’t want to read all this can just look at them and the dyno sheet and see if things look right. Bike is a 06 1800S3 with a 1300 final drive. I do not know what final was in during the dyno run (I can only assume the stock 1800 F/D was used)
— Exhaust - Cobra longshots with power port
— Baffles - Original thunder monsters that were bolted into the original baffle holes in the pipes.
— Intake - Maxflo by Maxair Engineering.
— Fuel Manager - PCIII Usb
Hello all! This is my first post on here but I’ve been lurking this forum for countless hours since I picked up my x a month ago.
It came with a good amount of documentation and oem takeoff parts and I’m still digging through things and finding stuff.
But anyways the entire point of this thread is a dyno sheet I found the day I bought my x. I had thought that the hp/tq numbers looked pretty darn low, at 88.39 HP and 101 ft/lb TQ
So the next day I went out with my computer and pulled the map off the pc3. Well the tuner seemed to have not touched anything in the lower rpm range (500-1250 or so) if I’m recalling correctly anyways. I was also having a lean bog when chopping the throttle in the low to mid rpm range that I noticed right off the bat. It was only an issue when “rev matching” on downshifts, so I decided to turn on the accelerator pump feature on the pc3 despite reading mixed opinions about it. And boy did that change my throttle response! It was worlds better tbh. Since then I have played around with the settings and tamed the accelerator pump down to the bare minimum while keeping throttle response as good as it will get on these big ol monster twins.
Aside from playing with the accelerator pump feature i tinkered with the buttons at first and then tweaked the original dyno map and my “Butt Dyno” runs indicated that more fuel in the low and mid rpm range seems to really wake the bike up! And I mean it went from pulling me back and lifting the front suspension some (before acc pump or tweaks to fueling) to literally pulling my A** back a couple inches into the seat and maxing out the front forks uptravel in a wide open second gear pull from low rpm.
All in all I’m starting to wonder if the original owner (Classicxman) asked the shop to tune for mileage and performance or if they were going for all out performance and just didn’t know how to get it.
I have switched back to the original dyno map without any modifications to it but left the accelerator pump feature on and set to 5% increase for 10 engine revolutions and been paying attention to my mileage at fill ups and I seem to be getting around 26 mpg (but I cannot keep my right hand out of the throttle) the best I got was a partial fill up that was 35 mpg. The problem is I can’t remember if I reset the odometer on that run🤦🏻♂️
Either way any and everyone’s opinion or advice is appreciated!

I respect and appreciate your feedback spike! I know you know your stuff and I’m just a youngin (27 this month) but have you ever seen a maxair up close? I feel like It’s probably one of the best flowing intakes out there for our bikes! It’s straight into the throttle body from all angles and utilizes the factory velocity stack to direct air into the throttle body. Extremely simplistic yet brilliant! As far as all the big name intakes out there for our bikes, the air flow has to make some sort of turn to make it into the throttle body (usually a 90* turn!) which isn’t going to flow as well as it could. They are going for crazy looks and max air shoots for best flow/Engine protection and simple design.
Oh and let’s not forget that you have the option to use whatever filter media you would like! You can buy sheets of foam from your favorite manufacturer and just cut to fit. It’s so simple to replace filters and you can choose how thick and how porous the foam is. Right now I am running UNI bf-6 bi layer material which cost me $23 for a sheet large enough to cut 2 filters. And will protect better than I will ever need it to.
You bet your sweet pippie I do! I’ll have to do that, but for now here’s a few for you vtx junkies! The red R in the background is my old lady’s new 1300 for those who are wondering.
Also on a side note, if anyone knows anyone with ultimate seats that aren’t studded I would be happy to trade them! Drivers backrest is in the right side saddle bag as well!
