Was watching one of the Bildon videos and saw him use a digital A/F ratio gauge in his Corrado. Now I'm wondering what everybody else uses. Do you just tune on a dyno and forget it or do you use an A/F gauge? I know some use EGT to tune but I don't know which would be better? So if you prefer one over the other, why? And lastly, which A/F gauge is better/reliable?
Thanks.
