Speed Works in Lewisville will give you 3 passes for $60. That includes a wide band O2 that plots your air/fuel ratios. FasTech does not have a wide band O2.

I'll be at LG's this weekend, and Speedworks the next for the dyno day. From my understanding, the only difference between the two are location, as each is located on one side of Dallas than the other. :cheers:
