Default GTR stock PSI?

Anybody know what they pump out from the factory? I've been looking around and haven't been able to find out.

I don't know the "official" factory spec. Edmunds review listed it as 10.1 to 11.6. I've seen dyno charts showing up to 13.5 with an average around 12.

Keep in mind the 26 could be taking into consideration that the engine is under vacuum prior to boost.

I can't even remember if I'm right or not

I think people only talk about the positive boost, such as 8psi... but the "actual" boost is the positive boost plus the boost needed to get to 0.

I think the numbers that everyone is familiar with is the "peak boost", and not the actual boost pressure.

I could be wrong.

I'm having mine tested before I do anything to it, but based on what I have heard from other drivers, they seem to think its around 10.2.
