I assumed when i payed almost 600 bucks for this thing that i would be able to use it and really notice a difference in the car, So far all i can tell it has done is turn off the shift light.... none of the performance data "tools" want to work, no 0-60, 1/4 time, est. hp. what is wrong with this device?? i'm about ready to return or sell it and get another predator
