Several have been used successfully - check Dynotech Research archives for one case. Way more adjustability (rpms, boost, accel pump), you can load and save up to 5 tuning maps, capture real-time stats with a button so you know where to tune, optional LED to determine load range, when accel is on, etc. You might be on your own for getting ready-to-go tuning numbers, but with a good A/F gauge and a little determination you will be rewarded.
