Wow!
I purchased the Vortex ECU for my 25 KTM 350 XC F to help with the flame outs and throttle response. I just completed my first enduro with the tune and all I have to say is Wow! I could not believe how much it freed up the suspension and made bike much better and less tiring to ride! If you are on the fence about purchasing the tune just do it! It will be different bike and you will get its full potential.

XPR is great!
Chad is awesome to deal with. He actually took the time to answer all my questions. Much better experience than I have previously had with the other main Tuner.

Get one!
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.
