reading plugs is a great tuning method also....dont depend solely on a wideband
Do you have a hood mounted gauge to where you can watch the FP. I prefer this so you can see what the pressure is doing under boost. You can have a weak pump that may supply good idle pressure, but not be keeping up with the demands under throttle. Another reason why I asked about the filter...will act the same way, both you will see on a gauge.
With a boost ref FP regulator you should see 1:1 rise on fuel prssure / pound of boost. If you dont have gauges, invest in some before you invest in a wideband IMO
