My 93 Z28 got totalled two weeks ago. I bought a customizable tuning chip (or Eprom), remote (which allows you to switch between tunes from inside the car: Antitheft, valet, performance, stock, nitrous, turbo, etc.), and the programmer from Moates.net in September. I paid near $300 for everything. This is a perfect setup for someone who is looking to tune their car to their own specifications or want to do this as a career. I am asking $210 shipped for this 4 month old tuner. It comes with everything. It comes with the RT tuner, but tuner cat has one to offer for a little more as well. email me at sillixboi@hotmail.com if interested.
