Ok I've done some research online and on old threads. I was looking at the Big gun rev box for 2 reasons 1. I dont have the cash for a Vortec and 2, I dont plan on putting my quad on a dyno to see which Vortec setting is best so I dont want to over rev the thing and loose HP. I've seen mostly positve comments about the Big Gun, but tose were back in December, any one have any problems in the last 4 months?

 

I have had one on my 04 DS for over a year and love it. I have had no issues and like having the 1000 more rpms. All I have done to my DS is pipe, jet, K/N filter and a +4 swing arm.

 

i've got an extra if ur interested
