rev box?!?!?!?!?!?

[mustang25]

i was considering prchasing a big gun revbox. It costs $130 and increases the rev limit by 750rpm's....is this worth it??? (i have already installed an exhaust, jet kit, and air filter)
-thanks

I have the rev box, and it is pretty good. It does increase the rpms very nicely, and on some quads, it increases top speed most of the time. On my 250ex, i would always hit the rev limiter in top speed, but now i dont because of the rev box. For the price, it is worth it.
