Frank,

Congrats on the IYF gauge. I've had one for over 3-yrs and have loved the constant/reliable feedback it gives me!

It sounds like the sensor is in the right place, now I would look at your Fuel Pressures, mainly:

1. System Pressure
2. Initial [Cold] Control Pressure
3. Warmed-Up Control Pressure
4. Under Boost Control Pressure

You'll need a set of CIS gauges to do this. There are many threads with pictures on how to setup the gauges. Like you, this was my fore' [sp] into the realm of turbos and higher-than-normal maintenance cars. This forum has been invaluable!

I would have to strongly agree with Mark [Lucittm] on this one - - you've got a great product!

One suggestion: look at the actual electrical connection [the plug] on the WUR. Maybe it's intermittent [got a bad connection]? Thus causing intermittent voltage to the WUR... Just a thought... Good luck and keep us posted!
