I run a lokar throttle valve cable on my A-518 on my carburated 360 magnum in my 91 half ton truck. It's been descent, it's a little worn out. But I spent a lot of time adjusting it and messing with it too get my transmission shifting the way I wanted it to. Which wore the cable out a little bit, and in my opinion thier throttle valve cable for the A-518 is over priced, I don't think it was worth 80 dollars. And like others have said my shift timing still isn't exactly how I want it, it's some what close but not perfect.
