Good point V. All tuners are a little soft on a mail order tune vs. a live tune. Sure, the mail order is leaps and bounds better than a stock PCM, but there is still a lot more left on the tuning tables with a mail order. The tuner has to be careful about tuning certain things that may end up harming your engine/transmission. A mail order is the first step above a stock PCM. And a live tune is the best thing for ya...
