The Sportsman ECU won't work on an 07. Mountain performance will reprogram your ECU with a raised rev limit for 400 bucks.

For 400 bucks, it better give me like another 25mph!

Ouch. How much speed do you gain.
The truth is you will need some motor mods to take advantage of that ECU. Getting extra speed out of these things isn't cheap. A DDP cam and Boonedocker controller will make a Big difference. I can't say for sure, but I would be willing to bet at 50 MPH you aren't even hitting the rev limiter, you are likely just running out of power. The limiter is actually RPM based.
As to price, a sportsman ECU (which won't work on anything newer than an 06 XP) will be in the $350.00 range.

it is definitely hitting the limiter at 50 doesn't seem to be down on power. understand about the speed cost money part though. not really interested in doing a bunch of engine mods though. thanks for the information.

If you are hitting the limiter at 50 MPH your belt may be slipping. Its not uncommon for 07's to hit 53-54 MPH.

For max performance you would like to stay off the rev limiter. If you have to much belt deflection [if the belt is to loose] this will cause you to have less bottom and top end performance. Just remember clutching is everything.

I do not know anything about this chip or the seller. You can go to the feedback section for this seller on ebay and email some of the previous buyers of this chip. Ask them what they think of the product and how well did the chip work. I would pick feedback at least a month old so the people would have some time to consider what they thought of this product. If you buy this product, I recommend paying for it through Paypal so you can get your money back if something is not as advertised.
