I don't know what your throttle cable looks like. I have had two twin turbos and have never had a problem. Oops, that is not quite right, once I had the cable come loose and that caused me to have a very fast running engine until I discovered the problem. As regards the company, I have recently been in contact with Eleanor, the owner, and was treated very nicely. She did, however, say that she had been sick and apologized for the time it took her to respond. Both Rob Grady and Don Steger regularly install and service the set-up, so call either one of them with your questions. You will not be disappointed.
