i paid for a dyno tuned, they even told me to buy spark plugs and a cooler t-stat so they can get more out of it. So i told them to install them for me since i was dropping it of, they sure, day later they call me and told me it was ready , so i go and they give me sheet with my hp, no torque a/f ect. when i pay they told me that i didnt need the t-stat and spark plugs because my car didnt need them, so i said ok and paid what i had to pay. checked my tuner later that day and it said that the last tune written was the one that i had already installed which was the performance tune, not a custom dealer tune, all perameters were untouched except for the timing which was advanced 1or 2 degrees more than i had already advanced it. i was so pissed that i did nothing, my fault but i think you all would like to know.
