how many miles before i should install my quadzilla box? i have about 4500 now.

 

I did mine at about 1000 miles.

 

You're about 4499 late!!!

 

Mine was BOMBed the day after I bought it. I only waited because it was nighttime when I got home from the dealer in NC.....

 

If you care about your warranty I'd wait (like I did) until the truck is broken in @ around 15K. I figured that if anything was defective or broken I'd know it by then. That advice is concerning a module/chip. I did the exhaust, gauges and intake right away. Dealer didn't seem to mind the gauges or the muffler, but I try to put the stock intake back before a visit. Enjoy.

 

That is good advice there. Unfortunately I had most of my stuff already from my 03 and there was no way I could wait....
