Yes it does it from atmospheric though so it start's around 14.6psi and goes up from there. For instance on mine it goes from 14.6 to 37.4 or about 23psi difference which is what a normal 05 should have.

I think that's pretty low for an '05. Aren't they supposed to be around 32psi max when stock?

I've heard conflicting reports on that, but John at Floor It Diesel said that's normal. He probably knows what the boost should be.

My wifes Yukon's engin light came on last week so I pulled the SG off my truck and hooked it to the Yukon and found a P0140 code O2 sensor problem. Then I put the SG back on my truck after I cleared it for her.

Anyone else notice on a 05 that the instant MPG is better if you don't put in the clutch and just idle to a stop? The MPG shows it being better with a the clutch engauged untill you come to a stop. Of course you have to be in the apropriat gear as you slow down.
