Hello again guys. Dune season is approaching, and I want to make sure Im going to get up ALL the big dunes at Glamis. Im ready to do some performance mods, but not sure who's the best and most reliable in AZ. I was thinking 840 kit, but I dont want to mess with Race fuel. I was told Id be happy with the 750 race kit. along with intake and exhaust. I really like what im hearing about the Muzzy pipe, but it sounds like its better suited for stock motor. Whos the expert in AZ.? Where should I drop this monster off?
