Yeah, probably....h:

I agree that the oil pressure, boost, and oil temp would be a good choice. If you have the money, a pyrometer will be 1000x more accurate for tuning than a light show A/F ratio running off the stock narrowband.

I had an A/F ratio gauge for a while, but I ditched it because it was as worthless as tits on a nun.

As for brands, stay away from those poopy ebay brand gauges. At the bare minimum, invest in some autometer gauges, but if you are a real baller, Defi gauges are pretty badass and will be the most accurate.

I have autometer gauges and they work fine. All I have is boost and oil temp in my bezel and that is all I really need since I have a wideband hooked up as well.
