Chipping a 1.8t, if I recall correctly, adjusts the boost on the motor. The
only thing allowed in STS is electronic or mechanical adjustment of the fuel
control system and the ignition control system, and you can only do it
mechanically or electronically, not both. With my little understanding of
turbo, adjusting the boost isn't mentioned, thus it's not allowed.

This brought up an "opportunity" I saw, and wanted to get some feedback on
if it is illegal, and I'm just not seeing it.  In STS, they say that ECU's
can be changed, but must retain the factory box.  They also include the VW
1.8T as a sample vehical for the class demographic.  The VW 1.8T benefits
GREATLY from a chip change.  Eurotech quoted my buddy 40-45 HP and 45-50
ft-lbs. when coupled to an open intake and exhaust (both STS legal).  I see
nothing in the STS rules stopping this.  Does anyone else?  Is this really
what they meant when they made the ECU rule?  210 ft-lbs... Just what every
street tired FWD needs!
