I need something that I can butt tune with that is fairly accurate. Any reviews or suggestions? I have an safc on a custom turbo setup on a d16a6. I have all the tuning capabilites, but need to get something setup so I can make it to the dyno at somepoint, I need to drive the car there though

 

The readings on air/fuel gauges aren't very accurate. I guess you could use one to get the car running good enough until you get to a dyno and use a wide-band to tune it. I have a Autometer one in my car and "tuned" the motor using that, then got on the dyno and used the wide-band. My air/fuel ratio was off by a lot, despite what the air/fuel gauge said.
