As low as the P500 is geared 40 mph max, I don't know what the point would be. It just isn't going to get that much faster for the weight that motor has to pull, Diesel conversion that's what the P500 needs 
Yea I was just seeing if anybody tried it to me it's set up just fine for my needsAs low as the P500 is geared 40 mph max, I don't know what the point would be. It just isn't going to get that much faster for the weight that motor has to pull, Diesel conversion that's what the P500 needs

Agree > 40 mph, then get different class machine. P500 to me as a small tractor, not racing buggy.
The power commander will not change the top speed that is programmed into the ignition what the power commander will do is change the mapping of the fi to give you more power
How much power gain will you gain with this device? Anything less then 25% not worse for me.

I am skeptical of what any "tuner" can offer the P500. First the P500 is naturally aspirated, the tuner cannot make any change to the intake airflow, exhaust airflow, compression ratio, or lift and duration of valve timing all of which are needed to make a truly noticeable difference.
All these tuners can do for a P500 is push more fuel mapped in a different manner and alter the ignition timing. Without increasing intake airflow and increasing exhaust airflow the tuner is handcuffed by the engines OEM limitations. Even if it boost HP by 10% you are still shy of 31HP on a 1000 lbs machine off the showroom floor. If it were a turbocharged engine that would be an entirely different topic.
The P500 is a torquey, nimble and fun machine. It will not nor ever will be fast, and even if you dropped serious coin into the engine to do so you are $4000 shy in proper suspension components to utilize it effectively.

" Without increasing intake airflow and increasing exhaust airflow the tuner is handcuffed by the engines OEM limitations." - like a bottle neck effect?

Exactly, to run at highest efficiency you fuel to air ration needs to be just so / so. If you aren't adding airflow why waste $400 on a plastic box to increase fuel flow? Poorer mileage? 2/1000th of a second 0-40? I mean what's the point.
I used to race Hondas a lot in 1986 I was getting right at 60HP out of a 250CC 2 stroke, and nearly 38 HP out of a 200cc Four stroke ATC engines and on that four stroke required some heavy porting and valve work with titanium valves and a 12.5 to 1 compression ratio, that may hold up a season in 20 min motos but I would not take it to the mountains on an 8 hour rides knowing I would never walk home.
By all means I think everyone should buy all the confidence they can afford but before spending $400 on a box that does effectively nothing noticeable invest that towards proper shocks that you may actually feel an improvement with.
I argee with you but on the 400$ air box thing lol where did that come from and untill you can get an exhaust for the p5 you will not get the 100% effect of the dynojet and also yes the p5 is torque but the power drops off fast in 3rd and up gears with a proper tuned engine that will help alot

Not $400 air box, $400 plastic box the "power commander" thought you Yankees had better comprehension skillz. See below it is a $400 plastic box

U can find them cheaper and its also the only way right now to "change the jets on the carb" u just cant swap out bigger jets on a fi system i know every honda ive owned was very lean from the factory and loved when i fed them more ive always used the dobeck tuners with great results right now this is the only option im not saying its a number 1 must do but we are very limited in power upgrades at this time
Isnt the p500 basically a foreman 500 engine/tranny? Looks like Dobeck has one for the foreman, wonder what the holdup is...or if it would work.
