Used them both. Both worked great until they failed.
Both were replaced under warranty. We'll see how long they last this time...
I actually preferred the Big Gun performance though.
I have an 07 All of the rev boxes were made for 01-05, but mfrs say they will work. I say something is different about the 07 and probably 06 models.
Symptoms are similar to fouled plug, too rich mixture. Put the stock CDI back on, it runs great. Go figure.
