I have a 1974 911 2.7 CIS. Following Wayne's suggestions, I swapped in 964 cams and 9.5:1 pistons. I also swapped in a CIS from a 1979 911SC and ported my heads to match.
The 1974 cis system had a throttle position sensor on the throttle body which causes the air/fuel mix to enrich when on hard throttle. The 1979 cis system changes the air/fuel mix by adding or removing vacuum to the warm up regulator. (When the throttle is closed, vacuum from below the butterfly valve is conveyed to the interior of the WUR causing an increase in control pressure leading to a lean mix. When the throttle is open, the vacuum drops and the mixture is enriched.)
Here's my question: would I get a performance advantage by installing my mechanical TPS from my old '74 throttle body onto my new '79 throttle body?
(I suspect that Porsche dropped the old style, mechanical TPS in favor of the vacuum and WUR setup in order to meet fuel efficiency and emission standards.)

Will a '74 style TPS give me harder acceleration compared to the '79 style vacuum/WUR setup?
