Wonderful unit and easy to use. It custom tuned my cold air intake, dual exhaust, engine, and drive train. Many other options available. My performance and gas mileage have been improved from 12mpg stock to 18mpg so far. My OD kicks in a 80 mph...She runs so tough now! I got a free hat which is HQ and a rebate also.
