Jerry, unless others are interested, we can take it off line.

I spent $4K on the DTA EFI parts. I spent another $2K on intercooler core, plumbing and misc.
So for $6k one can do EFI if you want to do all the labor yourself.
Personally it is so much work to do EFI that the $30K prices are very reasonable. I wouldn't touch the job for less that $10K
Power increase in my case was from 328 RWHP on a Dynocrap to 352 on a DynoDynamic. I also did SC cams with the EFI.

Stephen,
Thanks for the response. I think most of us on this forum would like to go EFI but there are so many bad stories from the guys that went first. I know that there could never be a single code that would work for all 930's out of the box but I was wondering if there could be a general code so that with the laptop hook up and some mechanical skills there could be a base line code to work from. The supplier, your company, would have to recieve from the customer certain parameters that you noted in your post, and then a base line code could be established and you would have checked all of the sensors and injectors for operability on a sample composite 930. From that start, it would seem that a guy with above average skills could take the base line and adjust it to fit his particular car. You mentioned the o'scope to test the injectors being $3500, but you could check out all of the pieces before you sent them out. It seems like we are just one "Geek" away from doing this. Some guy that you feed beer and chicken necks to to work on this project. C'mone Stephen, advertise for him!

Some of the things we have dealt with that are odd and damn near killed me, using an allen head as a pick up. In some cases we have used them in the past and it works perfect, the 944 uses the same thing. On one system it picked up the hole as a break and the other side as a second crank signal. Another, the front edge of the hall sensor signal was moving. Yes, moving and there was nothing mechanical moving!!! It was a sensor incapability to the ECU. We had a sensor that we placed in the dist. The field at 5K cause disturbance and the mag signal would pick up disturbance that pretty much never showed up in the scope. The fix was to place a hall sensor on the flywheel and cut teeth into it. I could go on and on. What to do if these things happen and the person behind the wrench is not use to EFI system. At that point we will suck according to those looking in. Frustrated owner and a pissed wrench.
See my dilemma?.

My gains went from 410rwhp to 510rwhp and 376 ft lbs to 500 ft lbs of torque. But, the only things original to the engine when I was finished were rods, heads and case. However, the above gains only give half the picture. The throttle response is completely different, the torque and hp curves are completely different and overall drivability (yep, subjective issue here) is completely different - all improved.
So, when someone asks, "what is the average cost for EFI", it can not be answered without a lot of other qualifiers satisfied first. This is similar to my real job at Merrill Lynch. Someone will ask me how to invest. Wow - until I know what you are looking to acheive and you understand the risks, there is no suitable answer.
