I wouldnt trust an email tune with my lawn mower only because I have seen what the vehicle runs like afterwards. Now if the car was tuned at the shop and then he later changed something I would say go for it but not with first tune.
I take my Craftsman units to sears and they send them off to be recalibrated. I do that twice a year and the last time I got mine back they gave me a print out in varying ranges of how off they were and how close they got after calibration.
If you drop one you REALLY want to get it recalibrated.
Way to butcher my name Skinner
