just removed from my car only as my recent pro-m ecu update now includes a boost controller

this thing is awesome!
3 stages of boost (waste gate, stage 1 via a switch, stage 2 via a switch)
stage 2 has a timer which comes in handy on the street if your turbo ramps up too fast

there's a small crack on one of the mounting tabs, otherwise everything else works and functions as new.

i will assist the buyer with setting up boost by gear if need be

here's the PDF https://www.precisionturbo.net/tech/instruction-manuals/NLR-AMS-500-Boost-Controller.pdf
