Hey all, I'm new to this, and sure this question has been asked a million times but would like some personal experiences and thoughts on my question. I recently purchased the superships flashpaq and seemed to pick my mileage up some but after updating it last week, my mileage fell on its face. And for some reason when I'm reading the vehicle the tuner cant read stock tire size, I get abs rx message timed out, cant read stock tire size. Has anyone else had this problem. Trying to get help from the guys at superships is like pulling teeth. I'm thinking of returning the tuner and going with something else. Any feedback on other tuners ?? I'm not necessarily going after more power, but I would like to squeeze every drop of fuel into mileage. Thanks for listening to my over asked question, Mike

 

i´m interesting in this info also...
