James brought his 350Z in from Chicago needing a few bugs worked out and a tune. We quickly identified and remedied a few problems, such as wideband signal being wired to the wrong input with O2 correction enabled. The car performed well on the dyno, and Hal was able to draw a nice chart on the Dyno Dynamics dynamometer – matching 486WHP and 486TQ.
