I've used both 93 Performance and Race, I can tell you there is a lot of pick up in the Race tune compared to the performance, race should be kept to track and highway driving, if you drive around town a lot, stick to street or performance. I remember driving on the LIE and doing over 80 just by driving casually. Also its bit of a gas hog.
My SCT tuner got hit by that firmware bug last year and I gotta get around to having BAMA resend some tunes, especially those 2.
