Not too happy. The part # is the same, but it doesn't look anything like the pic on the website that I ordered it from (SFX).
What it is, from what I can figure out, is a module that reads the TPS voltage, then uses the MAP to tell the computer to adjust the air/fuel mixture. There is no user adjustment, just on/off.
I don't notice any difference, other than acceleration seems a little smoother.
