[DeTomaso] How much has EFI advanced over the past few years?

I drove behind one of the German cars on the trip to Austria this summer, and it was an eye watering experience. I don’t remember who it was, but I believe that car would probably run much better and with less fuel consumption if it had a proper tuneup.  The engine would probably last longer too.

I believe Bill Wright has a FAST system on his Ford GT40 that has never run to his satisfaction. You could ask him for his thoughts. I think Don Byars has installed them on a number of Panteras. Ask him too. There must be someone in Spain that could make your car run to your satisfaction...????
> Personally, I had the Holley Carb Guy in Reno, CA set up my double pumper about 8+ years ago. I visited his shop, handed him my Holley in a box, answered all his questions, watched him do his magic, wrote him a reasonable check, took my Holley home and bolted it on my Cleveland and didn’t touch anything and haven’t touched it since then! I too am VERY HAPPY with how my car runs. The car has been on the chassis dyno at least twice, the last time about 4 months ago, and they’ve never touched the carb. Someone will have to pry that carb off my Cleveland after stepping over my cold dead body.
