Autologic is the best chip on the market for it's ability to alter pretty much everything the ECM has to offer. However, most of the Autologic tuners out there don't alter all of the options given. All though I also wouldn't alter as much as I would if I didn't have the car on the dyno. I do mail order for NA cars but not blown applications. Blown cars are so much more application specific than NA cars. DiabloSport would have to be my second choice for a chip. They are right up there with Autologic. I guess the best tuner to find is someone that isn't going to try to get you the best fuel mileage. These tuners are too conservative with the fuel enrichment scalers, plus they hardly ever tune the fuel curves on the base tables. Personally if your consistently looking for ways to bring more HP out of the car, I would look into something like the PMS from Anderson Ford. The learning curve on it is pretty simple and it grows with your needs.
