Pete,
I am kinda new at this small disp turbo stuff but my understanding is this, The PCM sees the high boost, as reported by the MAP sensor, and this is why it is dropped, you can "clamp" the MAP with a diode to regulate the voltage and trick the PCM into thinking it is only seeing 10psi or so, BUT you must add fuel or you will lean out. This is where piggy back fuel controllers come in, to add the extra fuel. I am getting S1 and a PSI-FI Power Paq, it has a built in MAP clamp, adjustable, and alot of other cool features, go to the SRT site and do some reading, there is too much to go into, and I don't want to give wrong info.
Tom
Please if I am wrong, some one correct me.
