Good product ease of installation
Nice selection of monitor items. I like the voices of items not normally monitored by in dash gauges. This intake temp, engine oil temp, throttle position , and oil efficiency. I have to disconnect it from OBD as it does not fully shutdown. It will drain the battery if not used. I drive theVette every 1-2 weeks.
so far I have tried it only on the performance mode and have not taken it to a track to see actual #'s ,however i have taken a short run inroads I normally travel abiding the speed limits and trying to get mileage and have exceeded normal mpg.up and down hills garage to garage and over 35 miles 31.7mpg.I'll try it on a road trip and reset it to best mileage program. I'll let you know what happens. I do hypermile when safe. It is great to have all the power and still be able to economies.
