I am impressed with the performance increase from this tuner. I run ethanol all the time so I used the premium fuel tuning program and my once sleeping dog of a navigator has finally woken up. Would recommend to all.
Good little gizmo with SIDE EFFECTS

Both tuning option definitely gave my Navigator noticeable power gains. Only problems are the side effects. Frist problem is that I got pinging or detonation which is bad for the engine on either settings. When I went back to factory stock settings, problem went away. Second problem is the slippage of transmission when coming off a turn or pressing on the gas pedal for sudden acceleration. There's delay in transmission engaging. I thought my transmission went bad but when I went back to stock factory setting, no slippage problem was present. Hypertech does have pretty good support though. I'm currently having the pinging problem looked at by their R&D team. I just wrote them today about the tranny problem. I really hope they can fix both issues because I love driving the car on either tuning settings and wish not to return it. But I only have 10 day windows until the 30 day refund expires.
