no, he has done it on late 80s and lots of 90s cars also.
and he is clearly mentioning that it can be done on any damn car !!
its simple because, its not about carb or FEP. its about AFM's (air fuel mixture) motion and compression. so this things will take place in cylinder, you dont have to do anything in other parts of engine.
i am trying to reach him either by phone or email, lets hope he reply ASAP , will surely update here whats conclusion.
