Overboost Regulater???
I ordered a DP-tuner with 40,60.and 80 econo settings,now I am wondering if I need a overboost regulater,and if a air compresser regulater would work if adjusted to 20 psi.I aso was looking at AIH plug for boost gauge and was thinking about making one,but I am not sure about the blue wire replacement to stop the code from setting.Can I make this wire and if so what do I need.

Another good option for the overboost regulator (aka MAP sensor regulator) is the one from ITP Diesel:

Here's what it looks like installed:

This is the best option as it doesn't bleed any actual boost off, so you're not loosing any boost as you do with a valve. It merely keeps the MAP sensor from seeing the higher boost numbers.

If I am thinking correctly, the ITP regulator will let the map senser see boost from 0 to 22 psi [what ever max is with out overboost] and send that info to the PCM.If this is true then the map sensor can read the boost across the board as well,whitch wouid let everything work as it is supposed to.This way of thinking makes the regulator a better choise over the pop-off valve because it is a small boost leak and the wiring harnness would show max boost all the time. Is all of this correct?

yes yes and im not sure about the electrical deal.
i had the pop off valve setup and it was about an inch (in the MAP line) away from my boost Tee. when it activated you could see the needle jump around and it set the code on one of the spikes. it wasnt a constant pressure to the sensor, it was 24 20 25 20 24 20 etc. the regulator- 23 23 23 23 23 23 23
