    DIY TBI Adjustable Fuel Pressure Regulator

    There are several other articles on the Internet about converting a stock TBI fuel pressure regulator (FPR) to an adjustable fuel pressure regulator (AFPR).

    What I did was fairly basic;

    I used a 9.0 mm mill end and milled to a depth of 9.0 mm. I used a punch to knock out the lower spring adjuster assembly.

    Make a slot in the adjusting screw for a flat blade screwdriver, and reassemble.
