Really good question. When I first got the car I installed boost/vac and A/F gauges to get a baseline. At road load 75MPH and under full throttle it's rich, <11. Looking things over I noticed this WUR had a manifold pressure port but it was not hooked up, just vented to atmosphere.

I hooked it to manifold. The idle A/F was stabilized but there was no impact on the rich mid and high range condition. To start I'll use it as is. I suspect I'll need to add a check valve to prevent boosting the diaphram.

One other find on eBay was an old school Miller/Woods single injector system which I used years ago with really good results on a 3.0CIS twin turbo install. I intend to install this system and use it when enrichment is needed.
