Power Hungry is able to take your current Evolution and convert it over to accept custom tuning. Basically, the same great custom tuning you can get from a chip can now be applied to your existing Evolution hardware.
In order to accommodate custom tuning, you will need to send in your unit for a case and firmware upgrade. If you have an older (game boy) Evolution, we can load everything up during the upgrade. If you have the newer dash-mounted unit, new calibrations can be handled via internet/USB download. Just let us know what you have and what you need for tuning... we'll handle the rest.
If you have any further questions, shoot me or Corey an e-mail and we'll get them answered for you.
Take care and have a great weekend.
