well first things first.. it installs in the computer on the pasenger side.. very simple install.. second the superchip i have when i bought it they programmed it right in front of me. what it does...well it opens up your secondaries sooner and increases your rev limiter to 7500rpm..to me it was worth the money i noticed a big gain...before u get this chip make it the last mod u do becuase i had to tell the what i had done and they made the chip for what i done
