I know how a turbo works, but im not quite sure exactly what a Turbo timer and boost gauge really do? Also, how do people adjust the boost from the turbo?

A turbo timer is a device thats keeps your car running when the key is pulled out of the ignition for a certain amount of time. A turbo timer is useful because if you dont allow the car to idle after it has been running you could burn up the bearings in the turbo.

A boost gauge shows how many pound of boost you are running (8psi)

You adjust boost by the wastegate on the turbo, either by a manual boost controller or an electric one

Hmm i know that you can infact adjust the boost you want to run Ex 3psi 5psi and so on. I do not know about turning it to zero, I dont think its possible but I might be wrong. I believe turning down the boost to 5psi rather than 8psi would save some gas but not a tremendous amount. Some1 will correct me if iam wrong.

I suppose it would just open the wastegate at 0 psi boost and above just sending all of the intake to the exhaust, and making no air go to the intake manifold. But weather or not a vacumm created by the intake would do anything else I don't know.

most turbo timers operate on the ratio of rpm:time. basically, if your motor is above a certain RPM, for every unit of time it is over said RPM, the engine is kept running for another unit of time. beit seconds, or fractions of a second, etc. that is the principle most operate on...just for a little more info about them.

less boost, less air going into engine. Less fuel needed. So better gas milage, right?
