Or is it -20 HP when disconnected???

Yep, breather for the battery....

Crap! You drained all the blinker fluid out - d'oh. Replace @ once.

I just checked, pulled it off and ran the car on the dino, dropped 28HP reconnected, back to 388HP. I guess that is the booster Audi never told us about :-)

Must have been disconnected at the factory to get the 360HP rating.... Go for it!

The hydrogen explosions in the trunk are propulsive though unpredictable

I'm sad to report that after plugging the little hose, there's no noticeable HP gains
