Default Codes: 16622-manifold pressure/boost sensor signal too high. and 17965 -postive deviation
These are the codes from yesterday. So this means i have a leak somewhere? I also had the intermitt power too low, but thats because the battery was unplugged.

Any ideas? What does the first code mean?

Default Log boost (block 115?)
from your recent posts it sounds like a problem with your MAP sensor. Compare what you log to what you see on your boost gauge.

Default First, couple of questions on your set-up
Are you running MBC only or in parallel to the N75?
Are you using a TCD on the MAP sensor?

BTW - 17965 puts the car in limp mode although your MBC set-up impacts how it plays out.
