which box would be the best investment in the long run? the quad is alot more $$$ and makes more hp, however i don't want to toast my clutch or have drivetrain problems.

 

I have used both on 03 trucks. The adjustable box from Quad is very similar to the one from BullyDog. On a 03 6speed 4x4 3500 dually with Scotty Air III and 5" turbo to tail exhaust the BullyDog box will make over 1300 deg pre turbo. The clutch has not slipped yet. A turbo is going on that truck this weekend. If I was going to buy a box for an 03 right now, I would buy the Edge EZ, and trade it towards an Edge Juice when they come out. Please PM me and I can give you some more information.
