BTW, I sold my Lucas 42's in favor of some custom built 42's. They use Bosch cores, and build them any size you want. They are all matched together perfectly, and flow charts are included. Hopefully it cures the funky idle problems I have with the Lucas. Talking with the guy there, he confirmed what I suspected that the Lucas suffer from requiring a higher minimum injector pulse with. I've had issues tuning several peoples cars because of it. It kills milage at idle and low load. I didn't have any issues at all with the Ford Green-tops, and this should work out to be an inexpensive alternative to the rising prices of the green-tops. I'll be evaluating these over the next few months, we will probably carry these on the WBS site pretty soon.
