You need to move because ... prison! LOL! And yeah, nobody needs to question that you practically bleed BLUE

As far as modding the SHO, this is what can be reasonably expected
http://www.ecoboostperformanceforum.com/index.php/topic,808Tuning has advanced since that post was written, people are pushing the boundaries simply with alterations to fueling regimens (i.e., ethanol blending, or race gas additive).
Intakes don't affect this platform much, the computer can handle it stock/tuned. Exhausts can free up more power, especially if you add a cutout. Downpipes is really where the restriction is, so doing that first out of the 3 will net you the most gains right off the bat. Doing all 3 will definitely require tuning to take full advantage. BUT these upgrades are not considered "major" upgrades by the tuners, so the initial price you pay for device/tune covers updating the tune for these items also.
Turbo cars = boost over atmospheric pressures. The SHO reads this boost using a boost sensor called a MAP. The X number of bars refers to absolute pressure. The boost you run will be = actual pressure in the manifold - atmospheric. Atmospheric pressure is 14.7 psi or 1 bar. So a 2 bar sensor (OEM for the SHO) actually refers to 1 bar of atmospheric + a maximum measurement of 1 bar of boost. A 3 bar sensor thus raises capability to measure boost to 2 bars or 2x14.7 psi = 29.4 psi. Most of this is to enable you to use the full potential of the turbos as their max efficiency is around 17-18 psi of boost. In addition, you will see boost spikes above that, which again would need the 3 bar to measure and control correctly.
Sorry for the verifications, but it was put into place after a particular severe bout of spam attacks. Should go away after 5 posts, appreciate your patience!
