XPR Custom Maps Reflash/Update

Been riding dirt bikes for 50 years. Just did my first ever ECU with the XPR tuned Vortex in a '24 XC-F 350. Totally different bike now, couldn't believe the difference at the track, pulls hard and smooth across the entire power range. I'm running the best overall power map for track and the Enduro smooth map for the woods on my factory KTM map switch. The XPR tuned 350 is so fun on the track now I might sell my KX450.

I installed this part along with the 2nd injector and vortex plus the cam chain tensioner. the power difference compared to to stock is un real!

High quality machining. There was a noticeable freer feeling in the rpms as they come off the bottom to ramp up in the mid range.

The power difference is unbelievable. After installing this in addition with the Vortex, the motorcycle has a much fuller bottom end and the power up top is huge. The build quality a top notch and the instructions are very informative and fool proof. It is a bit of an investment but the product is well worth is.

super easy to install, works perfect no issues, really brings the 350 to life. Paired with the exhaust flange and the best bang for your buck!

The XRP dual injector kit and Vortex ECU is a no brainer , If you are going to do any overnight basically plug and play modifications on your 250 other then suspension save your money and buy this kit you will be totally blow away with the difference it makes

Spoke with Chad many times he’s unbelievable with the service and follow up customer service he provided I rode ktm 350 many years and wasn’t happy with the stock Yamaha 250f I have to say his ecu 2nd injection a long with his recommended gearing 51 tooth rear sprocket really woke up this bike I have no doubt now about the bike and the price is well worth it every penny with that said I believe it’s check all the boxes and is as good as any of my 350s

Works terrific!

Works awesome!

Chad and this crew did a amazing job with my vortex for my 2024 kx450. All i can say is WOW! this bike rips and it is amazing how their mapping has made my bike not only faster with more power, But simply more enjoyable to ride as well. If you are in the market for XPR mapping, It's the way to go hands down.

Such a simple idea, and it also looks Super Trick underneath the cap cover ! Great Product, Great Company! Just buy it, you will not be disappointed!

Ordered this to replace the auto one and prevent future failure. I know what it says it does but wow it’s an immediate noticeable difference. Felt like 3rd suddenly opened up and I was able to stay in it longer. I put 6 hours on the bike the weekend I installed it and no issues.

Shipped fast, fit perfect and eliminated the vent line kink. Great product!

Quick delivery & easy installation also helps the bike breath a lot more along with my twin air

2025 YZ250F dual injector kit with vortex ECU mapped by XPR. Incredible improvement over stock. I am 215lbs and race A/B Vet off-road. I have a 25 YZ450 and YZ250. With the dual injector and chads maps, the bike feels super light and easy to throw around. The power is so much stronger than before and honestly, I may race my 250f more than 450 now. I can’t believe how much it improved power on just pump gas. There is no more “hit”, it’s just excellent power from bottom to top. The bike revs super fast, can pull a gear higher, and feels fast. Definitely worth the coin if you have it. Follow me on IG @wardognj
