boost guage really low
boost guage really low
I have a 2000 ssei and i replaced engine with used one, it seems to run fine but i noticed that the boost guage needle isn't in the middle at zero it is just above the -10. With the other engine it was in the middle, it seems to be working fine it goes up when i give it gas. I've replaced all the gaskets on this engine. So i don't believe it is vaccum leaks. I was wondering what controls the boost guage.

Re: boost guage really low
at idle? At idle it should be at the -10 mark, and go up from there. The boost bypass valve allows air to bypass the supercharger under light load and at idle to improve fuel efficiency.

Re: boost guage really low
Think of the boost gauge as a throttle % guage. The harder you push, the higher it goes. -10ish would be no throttle. 0 would be 50%, and so on.
