A40 treated with ZX1

Well I could not believe the difference int the A40 it was like someone had changed the engine when I was not looking. It ran at lower RPM, sounded a lot better, had better MPG but the most amazing thing was it went!, I had trouble getting 60 mph out of her, now she was doing over 70mpg, I know that 70mph is not lightning speed but for my old A40 it was a small miracle.
