The funny thing about it is that the car dyno'd at 150HP with the broken DSI. No other mods were on it aside from the drop-in K&N air filter.
The DSI manifold goes to the "short intake runner" position by default if the linkage breaks or if the cable breaks or is disconnected. The short intake position is where peak horsepower occurs - 7,000 RPM. So your car would show peak dyno hp even if the DSI were disabled.
