After you have the parts installed and the car running well enough to drive it, take it to the tuner to do the rest. I am surprised there aren't "good" EFI kits available for 911/930's.
Man! This is an eye opener. I thought there would have been a 'formula' so to speak - some guide to follow by now or perhaps an aftermarket bolt on kit, but it looks more like black magic from what I am hearing.

The reason I asked is, I am trying to determine what the next step of performance is beyond headers, cams, an intake and dropping weight? EFI sounds much more costly than I imagined.

Factory stock other than k27 turbo, B&B headers, GHL exhaust, Tial F40, 1 bar wastegate, MSD 6A ignition, 8" and 9" Fuch upgrade, H4 Xenon headlamps and a 930S steering wheel.
