I was looking at autometer's site, and they explained that when you are at WOT, that the computer goes off of the fuel tables, and not off the oxygen sensor, so with that, can you tune your car with one of the gauges? Or will it just always read rich? Seems like it only reads a very small range, i thought maybe this would help with tuning in my nitrous kit, and keeping an eye on it so it doesn't go lean or too rich, so would this help me or not? Thanks.
