I will be the first to admit I am no expert when it comes to these tunes. But I dont think it takes an expert to go out on a limb and point the finger at the tune when I have 16k+ miles on the car with zero problems and zero limp modes and then a limp mode within a week of adding the tune. Dont get me wrong, I knew this was a realistic possibility when I ordered, but that doesnt mean I am happy about it.
