I believe uprev did leave me with a stock tune but I do not remember which map it was for sure. Not to bash them but UPREV has very poor customer service. You cannot get them on the phone ever and they do not respond to emails either. I need some guidance please. Thanks

i just got inspection/emissions monday and i passed with test pipes and tune.
only time i ever had a problem was the one place put my car on a lift and actually saw i had no cats then failed it.
but without them seeing the cat delete my car passes everything.
