Assuming you have an </= 88 turbo, you have LH 2.2, and an adjustable AMM. There is a small disc on the AMM which you will need to pop out. Sometimes they have to be drilled out.
Connect a voltmeter to pins 3 and 6 of the AMM, and turn the potentiometer (behind the disc) on the AMM to whatever you want. Without water injection, I set mine to 280 - 300 ohms (and removed the screens) with that same set up.
You'll also need to bypass/bridge your overboost fuel pump cutout switch (which comes on at about 15 psi).
Also, try my BPC modification for higher boost with decreased spool time.
