Definitely. There was another post which pretty much bears it out - a particularly successful build :
Engine Rebuild EFI results
He has EFI + the Carrera manifold.
At 1.0 bar (.85 bar indicated), 500 at the wheels vs. my 438, and my CIS is pretty much optimized.

A guy here in WA State had MOTEC EFI done wih the stock throttle body, stock manifold, and a so-so turbo (don't recall the make and model but at the time I recall it was surprisingly average) -- and got about 420 RWHP. FWTW.

Highway mileage @ 70 mph on my former 911SC with Vario 3.6 was about 25 mpg, the 930 maybe half that.

On the other hand, in 2007 there are tools available to build an optimized CIS system which works really well.
For about $1,100 in equipment outlay, the CIS system can deliver enough fuel and can be accurately tuned to result in an AFR range which just may make one think about keeping the basic system that they already have.
I really like my throttle response and "what lag" feel.
