Does exactly what they say it will. No more annoying 4 cylinder mode! Only thing I wish it had was an on off switch. Can't believe that if they were smart enough to design this device that they couldn't include an on/off switch. The plugging/unplugging issue is a PITA if you don't drive your vehicle every day. Hopefully they will come out with a fix.
