I just bought a 2005 Duramax Chevy and am seriously thinking about adding a chip/exhaust/etc. to it. What does everyone recommend? How does the Banks system compare to the Edge? I'm also looking to hold onto this truck for 5+ years, so I'd really prefer to not blow up the engine or the transmission. I am assuming all of these products void the warranty. In the event of a problem, can you unplug them, get warranty work done, and then plug them back in, or will the truck's computer alert the dealer that the chip was installed? Thanks for any info.
