Message: I have a Superchip for 98-03 gas trucks, suvs 5.2L and 5.9L v8 engines they retail for over $400 I'm letting it go for $200. I've only had it for about 2months on my 00 r/t. It works great, I dropped about 3 tenths off my 1/4 mile time. It's still in the box with all the instructions. I ran into money problems thats why I'm selling it.
