Stock boost

What is the stock boost of a 04 CL600?
Is the ELM 327 odb2 scan reader accurate at giving the real boost and what should be set to, MAP, MAF or ALT to read most correctly?
Thanks.

I finally got the BT elm 327 working with the correct measurement gauges. I have been curious of the numbers on everything and also thought my car seemed to have a bit more stock power then other, now i know why my boost is hitting very consistently to 15.5 to 17 psi boost. I seen others that would hey 14.5, 14.7 and that was suppose to be good. So I am good at my stock numbers now I know why my TC and ESP comes on so aggressively. It comes on so hard right after I hit full throttle at a dig I get thrown back in my seat but when it starts to spin the power cuts so fast and rear brakes hit so hard that I get thrown forward and would hit the steering wheel if not for the seat belt locking up. It happens so fast that it starts to hit again and push me back in my seat before I can pull my foot off the throttle. It was really startling the first few times I thought something broke. I had to get 295 width sticky tires to get enough grip to e en enjoy to power it can give.
I can't wait until I get my tune installed just waiting till I get my exhaust squared away which I am doing now.

Most will be slow as it must use ISO 9141 which has a slow data rate.

Later cars (221/216) use 11bit can and logging is much faster.

Torque has an iPhone app version, but it is WiFi and requires a WiFi version of the OBDII dongle, like this one from BAFX:
