Stock Turbo Limits..... - Page 2

Yeah, it would be reading less than the maximum so the fuel tables are still maxed out and not defueled.

It does sound like you read the sensor that started it at the atmospheric pressure, 14.7 at sea level? So I would be inclined to think you really only have a max of 18PSI of boost, which sounds right for a stock 7.3 Superduty.

If you look through, there's another sensor to pick that'll start you at 0 PSI.

I was hoping my truck was special.

If you had a real chip, you would have a special truck

J/K, I had to say it. Say Hi to Mike for me.

Keep Strokin'

It is called "manifold gauge pressure"

I will.....just don't want to put a real chip in until I have guages.

here's another question.....If you tap into the MAP line for a boost gauge, how come you are reading true boost instead of boost + barometric press like the PCM is?
