I'm all ears so let's hear any ideas?

CIS is "so good" on a car for drivability and gas mileage>911T what the original post was about and also are about "touring" what the T stands for in 911T.
911T's were never about power.
The S and RS with a lot of cam overlap could use MFI that did not have a mass air flow sensor and were not bothered with S and up cams.
Those people and Porsche opted for the MFI in that circumstance and it delivered in spades.
Do not confuse the T and the S and the L as the same car with the same engines and purpose.
The CIS is a better fuel deliver system for the T model 911 ( The 911T was discontinued after 1973) and commands a premium over the MFI in 1973 T 911.
