I went to have the car tuned today, using an AEM boost solenoid to increase boost from 8psi to 10psi. Unfortunatly the AEM boost solenoid wouldn't actuate. We were able to crimp the vaccum line to increase wastegate boost, but the solenoid, even at 85% duty, would not move. We checked the wiring, and put a volt meter on the connection (C10) on the EMS - no power was seen on this wire. After a few hours of troubleshooting the tuner said he would call AEM on Monday, and I will try again on Tuesday.

The problem seems to be internal to the AEM, either something in the software (unlikely, as the tuner has used this boost solenoid before), or the unit itself is defective.

He did tweak my old map slightly, and compared the car without muffler to the original dyno run, with the old magnaflow, and found a pleasing increase in power. Here is the dyno chart comparison:



(note the gain of over 20rwtq at 3500rpm)

And a camera phone video of the initial run:

This morning I went to 'JMC auto repair' (a muffler shop) and had a exhaust pipe fabricated for the wastegate. Prior to this pipe the wastegate was dumping hot exhaust on my ebrake cable, which was melting away the plastic.

Here is a picture of the pipe:



You can also see the melted ebrake cable on the right.

After this I went to Niguel Motors, where we disabled the VVIS system by placing a cap over the #3 vacuum line. Then it was off to the tuner.

We ended up not using the boost solenoid to increase boost, the car made a suprising increase in power by disabling the VVIS system, to the point where increasing the boost, while it would have created impressive numbers, didn't seem necessary.

Here is the final run, at 8.0psi (418.8rwhp, 317.3rwtq):
