Lowest possible safe boost?
I was wondering what is the lowest amount of boost are cars can do? I want to make turn my boost all the way down with the Xede but I don't have clue if I can damage something if I set it too low. Anyone know how many lbs of boost would be the least amount I can run safely?
Dude, that's the wierdest question ever 
Well, you can turn your boost as low as you want It won't hurt the engine. But remember, the boost will go as low as the wastegate permits. usually around 11- 12 psi. I think the car might run too rich, if you keep the same MAP that runs on 19 psi.....

See that is what I was looking for. So probably 12 psi because of the wastegate. Actually I was thinking of making a whole new Map for the Xede running at 12psi and then lean it out. That way I can try to create a gas efficient map. I need to get better gas mileage than the occasional 20mpg I get.

Exactly a low boost for valet and friends, also for trips to work in the morning. I don't need to be driving crazy in the mornings, I don't usually wake up until I get to work.
