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.

Wish I would have bought it sooner!
I’m on my fourth 350, and I finally decided to pony up and buy an ecu from XPR. All I can say is, WOW, what a difference it makes! No more flame outs, and the throttle response across the whole rpm range is incredible. It can lug like a manageable 450, but still revs to the moon like a hopped up 250. It just feels so crispy. Worth every penny - take the plunge and you won’t regret it.
