curious, what kind of piggyback are you running?

there is a pretty cool wideband A/F gauge available from Innovate that will let you know exactly what is going on in real time & tip you off to problems before any damage can occur. there is also the lower cost DIY kits from TechEdge.

yeah, all the new electronic widgets now on the market are pretty expensive, but so are replacement motors. I would think on a factory n/a engine that now sees boost & is driven with any regularity, some kind of monitoring would be crucial to help keep things from going boom.
