Hoping someone can help me understand boost?. I understand it uses the exhaust pressure to spin turbo to push more air into the engine..But why have a gauge for it? Only thing I can assume is for the people that are running it down a truck or pulling 20k+ trailers. I plan on for now pulling about 10k or less. Chipping for MPG not for power. I am not running it down the track.. I guess you could say I will not be pushing it's limits in any shape.the only gauges I can think of of getting is pyro, trans temp, and soon rail/fuel PSI.Also what makes boost change? Putting pedal down? Pulling a trailer up steeper hill? I'm new at the boost so a guide for dummies would be great!

Should peak about 30-32 psi.

Thanks. My powerstroke (last diesel) began at 19.5 factory stock, in fifth over. After the ford dealer finished, I had only 13 lbs of boost, made mods and added a programer to get up to 17 boost.

With a evaluate you will see what is not regular right away and be able to fix it before a garden hose might strike off and keep you seated on the side of the street.

I drive with my boost guage. Max boost is 100% power. At 75% boost my auto trans will shift down with a 17K load. If I am pulling a little rise, I may back out to keep the trans from downshifting as it will only up shift after the hill and that wasts fuel. They are much cheaper than a pyro and tell you more about power usage. My last old antique 1991 can only handle 60% boost for an extended time before the trans will heat.

That's only true if you don't have a wastegate in operation. With a wastegate you can hit max boost at less than max power. The boost gauge does show work better than an EGT gauge, but the pyro is just as important for motor longevity, if not more important.
