cost of a Tune

[kglowacky]

did a trans rear case manual speedometer modification to use my org. speedo . it works well not sure it is perfect but close enough. Shift points seem to be ok. I don't drive it hard just cruse around town. I could send the ecm back to the guy that set it up if it is necessary to change the ratio. If that makes a big a difference, Thats what I don't know.
