Frequently Asked Questions
Let customers speak for us
Sent my Vortex to Chad to get some more top end power and over rev out of my CRF250. Absolutely knocked it out of the park in meeting my needs with this bike. A+ and highly recommend! Communication is the best in the industry as well!
Couldn’t be happier with the quality of product. Super easy installation!👍
Our new race bike got the 2nd injector kit and Vortex X10. It truly changed the bikes overall performance and power delivery. We also tested the Vortex on the single injector and it was night and day difference. For those looking to have single injector but more gain then the Vortex X10 is the way to go. Set aside from the kit, customer service was fantastic and had answers to all of our questions. We are very impressed with the results from both XPRs services and quality!!!
Installed the XPR mapped vortex with an FMF full exhaust system. The combination made noticeable improvements. The bike now revs quicker with a slightly better mid-range and much needed improvement to the top-end.
Had to buy it due to the PC system being bigger, and hotter than stock. Super easy to replace. Took less than 10min even with draining and refilling the coolant.
Vortex ecu with xpr maps and cut air box = whole new bike ! Way more torque, more midrange , it will pull 3rd with stock gearing with a stock exhaust , on pump gas I can only imagine what a muffler and race fuel will do , if your not sure to pull the trigger on a vortex from Chad quite thinking and do it !
Bought a vortex and definitely well worth the money! Very satisfied with tunes and overall purchase. Had some questions and Chad is full of knowledge and great with his customers highly highly recommend!
This thing rips now! Excellent customer service and response with any questions I had.
Just received and installed it bike runs crisp and the power curve is smooth and pulls hard all the way to the limit plus it starts alot easier then before
Cleaned up the already good engine to make it even more all around power. It’s super crisp and worth every penny!
Opened the bike up through ever gear, reduced engine breaking, increased limiter. Overall better handling and power from the bike
Excellent work very impressive and very informative and helpful before and after sale I’ve used other companies that claim they can do good things but Chad is hands down the best in my opinion
