Thanks for the feedback, Phil.
The undertray
will re-appear on the car at some point, but my efforts will be on the rear of the car again before the bottom.
As for the
ScanGauge issue, I know you tend to stick to just the Aero forum here, but there may be good news coming down the pipe in that respect: there's another active thread going on in the
Instrumentation forum where members much smarter than me are discussing building an electronic
ScanGauge equivalent that would work in your truck (and any vehicle with fuel injection & a Vehicle Speed Sensor). I'll keep you posted.
