Not having much luck finding an official source for the 180hp TT's factory boost pressure. Audiworld FAQ states it is .8 BAR from the factory. This equates to 11.6psi. However, a few tuner websites state the factory boost as 12psi. .5 psi is significant, so I'd prefer to be sure before I explore ECU upgrade options.

Thanks.

I think not. They're pretty much saying the same thing.

Most of the tuners offer 1.1 bar chips, and *that's* a good deal more important than whether you started at 11.76 or 12 psi, I think.

Electron Man

1 bar = 14.5 psi...0.8 bar = 11.6 psi

PanTTher

They just rounded it up, that's all.

CMH

Actually 1 bar is really 14.7 psi

To be more exact...
<tt>
1 atm = 14.6959487755134 PSI
1 bar = 14.5037737730209 PSI
1 bar = 29.54 in Hg
1 bar = 0.986923266716013 atm
1 in Hg = 0.4912 PSI
1 in Hg = 0.03385 bar
1 PSI = 0.0689475 bar
1 PSI = 2.036 in Hg
1 PSI = 0.0680459 atm

I think you type a wrong number in there somewhere - a 2 instead of 7 :P

lol ;-)

Since 1 in Hg = 0.4912 PSI you'd feel more performance change when a high pressure front moves in after a rain storm.
