Stage 3 vs Stage 2? - AMR's newest Stage 3 rev box not only removes the limiter found in the stock CDI unit, it has the most Aggressive Timing Curve possible, built in. The Stage 3 box will give the motor better throttle response than the AMR Stage 2 (and most other CDI units on the Market) We recommend the Stage 3 if you have any Exhaust / Air modifications or plan on adding them in the future.
BADA$$ this box I put on my 05 xtreme cr2 guy cooper replica 125cc pit pro, like a tricked out crf 5o and it made a huge difference and for the money its just insane. really I didn't expect much but I was blown away and have fallen in love. ive rode and raced mx most my life and I also stunt gsxr 600s. I am a very picky rider and can tell the slightest changes in my equipment and this box rocks. I had a big gun on my 250f and it helped but not like this box did on my pit bike. I had to relearn my circle wheelies but only took a min to get used to all the extra throttle response and new found power. id say im an above average rider and ive won a few state championships in the local pro classes in mx so I ride a lot and ive used so much stuff out there its crazy. no more hesitation or rough above idle its straight smooth and super responsive and its like im on a lill tricked out 250F lol. If u want ur bike to rip then I say this is a must and it made such a difference I highly recommend this product. Thanks AMR my play bike rips and time to go rip it up
