Yes the big Gun is built by Procomm, but it is done differently for Big Gun, hencs the reason it works. But I would still spend the money on a Vortex, you can change the map just by flicking a switch, perty nice.[img]i/expressions/face-icon-small-happy.gif[/img]

 

I had a vortex on my predator and it also kicked back, Go figure!!

 

We had one on Tracy's Pred and never had a problem, it ran great.

 

My Vortex hasnt had a prob, neither has my buddies on his CR730 raptor.

 

I wander why mine kicked back was it cause it was high compression engine or somthing else?

 

maybe your idle is set too high? too much fuel doesn't help when there's a false start
