Double check the wires into the DISA valves and pony up for the better gas. I always thought that once you tune the engine you weren't able to safely run lower octane gas. When I rebuilt my 3SIM I missed a wire and it made all the difference. The power delivery looked very similar to your power curve.

Guys I ended up fixing the DISA issue a few weeks ago. I was cleaning out my air filter and I decided to look around the engine bay. The little connector that goes into the first DISA valve was not plugged in properly - it was turned the other way and it never "clicked".
I turned it around and clicked it in, praying that this would be the fix. Get in the car, start it up with no problems, warm it up and take it out. Instant change in performance and responsiveness. |

Ok guys, this is done now. I took the car to the dyno about a half a month ago but I was waiting for them to send me the dyno files so I can do some high res screenshots etc and make the YouTube video. It's done now.
The car with the fixed DISA + 91 octane made just short of 40 RWHP extra on the stock motor. When it's especially cold outside and the car is nice and warmed up, my god it's got some balls. New Youtube video: |

The plugs were done like 35-40K ago and the VANOS solenoids I cleaned about 7 months ago or so.
