According to the eBay listing,
"AMR's newest Stage 3 rev box for the Honda 400ex not only increases the rev limiter found in the stock CDI unit, it has the most Aggressive Timing Curve possible, built in. The Stage 3 box will give the 400ex better throttle response vs the AMR Stage 2 (and most other CDI units on the Market). Stage 3 is recommended if Exhaust / Air modifications are installed or if you plan on adding them in the future."
I guess the Stage 3 increases the rev limit to 1200 RPMs over the 750-1000 RPM increase you get with the Stage 2. My question is, are the gains between the two going to be that significant? The Stage 3 is selling for $89 while the Stage 2 is only $35. They also have combo packages that includes both a CDI box (Stage 2 or 3) and a Monster Coil. Or you can buy the coil separately for $69. The coil is supposed to give 34% more energy to the spark plug and increase the throttle response further.
So, what should I do? It'd be $145 for the Stage 3 + the coil and $105 for the Stage 2 + the coil.
