As for losses I know several people who have done this the only down side is bad gas milage because both runners are open at the same time. It does help acceleration one person running a 50 shot ran a 13.9x on the stock tires

Whoa....I gotta correct you on this. They *ARE* controlled by the ECU. The ECU has one wire that goes to the intake runners. The Runners are mechanical, however, they are controlled electronically. The ECU sends a 12V signal to the intake runners at all times when the RPM is under 5000. At 5000rpm, the ECU cuts the 12 V signal to the intake runners, which allows the system to apply vacuum to the solenoid, which in turn moves the plunger and changes the runners.
I am currently working on a setup to have the runners switch at a different rpm using a switch. I can get it to work but can't get the RPM right. The switch seems to have a mind of it's own. But I'm working on it, and will post results when I get it figured out.
