wide or narrow band a/f?

Wideband A/F is my personal favorite, but I also have a fuel pressure gauge that has been incredibly insightful. If I could only have one, it'd be the wideband A/F. I look at it way more than my fuel pressure. Both have been a great asset to my tuning efforts though.

fuel pressure gauge just really makes narrowing down problems a lot easier... a/f gauge is the best thing you could buy for tuning...
