Installed this in my 2006 Ford Expedition. I set it for 87 octane fuel. It really woke up the engine performance and I am seeing 2mpg better in town and 3 to 4 better on the highway.

The down and dirty: Yep, got a nice 93 octane tune. The iPhone interface to do this is slick and I would not say slow But: After a few days the module you get that plugs into the OBD II data prt died. It flickers as if it will startup, then dies So: I am very pleased with the tune. The power increase is noticeable and the shift points aren't ramped up to obnoxious levels. i have not given cust supporter a chance to rectify.
