Street Tuning

While I had my car dyno-tuned after installing the supercharger to get the A/F ratio, spark curves, and fuel tables safe for wide-open-throttle and dragstrip duty, I went back to the tuner for a second session that was street tuning for automatic transmission shift points, line-pressure, and stall converter lock up points after flash. We also fine-tuned timing after driving the car hard on the streets to account for different loads that the dyno couldn't capture.

Ultimately, I feel that it was a good, safe decision to do both (dyno & streetability tuning) to better set up the car for the track and daily driving.

I do street tuning first on my own car, then fine tune on the dyno. the dyno tells you whether your afr was beneficial for power, something you scanner can't show you. your dyno also doesn't test uphill and load while the car is turning. dyno tunes are usually better IMO.
