Anyone know how much boost a GN made from factory?

My GN is currantly pushing 10 lbs of boost and I was wandering what they pushed straight out of the box? I had to replace my turbo and I put a little bit bigger one on and turned it down to 10 lbs, Someone told me they pushed around 11 lbs new, Is this about right or is it a little more than factory?

Thank's Dean
 
On 93 pump gas you should have no problem running 16 psi, but get a scantool and tune it and you can get 18 psi out of it on pump gas.

what fuel pressure are you running to get 18psi on 93 octane. i have to set my fuel pressure to 47 line off, to get mine to run 14psi on 93 octane. with 0 knock and around 820 02 numbers.

but you can never tell if your actually getting 93octane from the pump:rolleyes:

A LOT also has to do with the chip you're running and it's associated timing curves. Mine for example has the WOT timing in the 19° area in 1st and 2nd gears, and 17° in 3rd and 4th.

This allows much higher boost levels on 93 octane gas. I'm able to run 20# in 1st and 2nd gears and pull it back 17# in 3rd and 4th.
 
Somewhere in the 12-13 range from what everyone has said. I know my car with 9000miles on it read 13psi on the vdo. And it was solid on there it never over shot and came back down.
