Title: Super ultra magnum premium elite high performance module
Post by: Complete Loser on July 30, 2010, 10:09:15 AM
Anyone every used this thing? Im getting ready to (hopefully) rebuild my squirrel cave, and ran across this looking for parts.

Seems like snake oil to me...  Those chips typically just alter the MAP voltage.

negative, that would require power, ground and output (even input and rpm signal in some instances but that's a whole other animal) - this one only has 2 wires

It's on the manifold towards the firewall side of the TB.  I took a picture of one a few years ago.
