This couldn't have been easier to install on my wife's 07 Monte Carlo SS. Taking my time it may have taken about 30 minutes. I also have the K & N FIPK cool air intake installed. This MAS looks just like the stock unit on the sexterior and does exactly what it says-it saves gas on cruising mode and opens up performance when wide open throttle. On level ground at a pace of 40-45 mph it is giving us 35-40 mpg according to the ECU readout in the dash. This is up from the 30-35 prior to install. This is with the 303 hp 5.3 LS-3 engine with displacement on demand (V8 to V4). This MC SS now does 0-60 in about 5 sec! And has been giving us 22.6 mpg in city driving here in DFW, TX.
