You will be fine. The only reason with a boost fooler you would not see true boost if if you hook it up after the fooler. The diode fools the PCM not the turbo.

i hate the resistor mods.. Made me blow a hpop o ring. Im assuming you are talking about the ones you plug in to fool the hpop to pump more oil and get a little more smoke right? Your a big fan of those arent you ryan?

No, thats the 10k mod. This a 4.7v Zener diode on the MAP sensor to work as a boost fooler.

If I read the original post correctly you have an electronic Boost gauge that reads from the map sensor. So in that case a mechanical fooler will cause it to read low AND the Zener will also cause the gauge to freeze at 4.7v even though your actual boost will be going higher. Only way I can see around that is to either install a mechanical gauge or a second map sensor.

^^^ what he said. You are limiting the sensor from reading anything above 4.7v which translates to about 16psi. This keeps the PCM from defueling. It will also keep your gauge from reading anything above 16psi, since you are reading the same signal. You'll need a mechanical gauge to read properly.
