I got almost 10 from going to EFI. And from what I've seen I tend to believe that the PRV in the DMC-12 is exhaust bound. With the cat out of the way and a free flowing exhaust I'd be willing to bet you'd see a substantial increase. If you send me a system I'll dyno it for free... :-) But I probably wouldn't want to send it back. Jim 6147
