I use the 9drive on amazon. It is great. It had a ev mode and race mode. I get good fuel economy in the highest setting with a intake and quantum solenoid track.
Love it, i got the Shiftpower for Hybridpit.com night and day difference. Its like a boost of power mode and more limp (slow acceleration) on eco more lol. MPG varied a lot depending on your driving style. You can decrease the MPG a lot on race mode or increase the MPG on eco mode
