sounds like some good advice ... im a little confused on how these dyno operations work. every place i explore information about rents out the dyno. now, when you rent out the dyno, is there someone there from the facility with you? the main thing im concerned about, obviously is the a/f ratio. i have no idea what i would be looking at if noone was there! sorry if this is a dumb question, im still learning about everything. one last thing, if i did get a chip, i would bring it down to the dyno facility and they would tune it there, correct? how does this whole operation work? thanks for bearing with me..
