Yeah, I have the tuner and loaded up a canned 91 no DOD tune, but I haven't forked over the $125 for Lew's custom tune.

I'm doing the custom lew tune right now. Just did my first driving log.

So far, the $125 is already worth it. The predator made my car faster on its own, but the first tune Lew gave me made it run even better. Already a small jump in MPGs from the stock diablow 91 no DOD tune. Definitely worth it. He's a great guy to deal with too.
