Minimum/Maximum Gauge Readings?
I have a 2002 7.3. I have the 6637 air filter and a 4" turbo back straight exhaust. All of this chipped with with a Diablo Predator. I am getting some gauges in the next few days and was wondering what the minimum and maximum readings should be. For example, what temp should I see on the Pyro before I pull my foot out? What about boost and Trans temp?

Pyro I have heard you can stand blasts in the 1500 deg range for very short periods and sustained you want to be below 1250 deg. That is all pre-turbo of course.
Tranny temp is usually 70-80 degrees below ambient temp when empty. You want to watch and keep it as far below 200 deg as possible. They say that for every 20 degreees below 200 you keep it, the tranny life doubles.
Boost will be anywhere from 22-28 or so. Some here have seen 30psi with the stock turbo. You need to get an Overboost annihilator or your trucks PCM is going to defuel at about 24-26psi anyway and throw a code.
