Boost Pressure ??

[Optimus247]

I may have known what the Stock S6 runs for boost pressure ... and even the APR Stage 1 pressure ...

The only information that I can find only shows the Hp and Tq ... which is what really matters ...

If anyone could re-enlighten me of the Stock boost pressure and the APR stage 1 and Stage 2 ...??

Found it ... well stage 2 & 3 ...

Not sure about those numbers, my S6 does 14-16psi boost.

In the early days APR used to show their boost graphs on their website but I think have since removed it.
When it was up it showed peak 10 psi stock from about 4000-6400 RPM
Stage 1 showed peak at 20 psi @4000 RPM dropping to 17 psi at 6400. (Both on 93 octane)

I'm willing to bet the discrepancies you see is perhaps part of the reason they removed it.
Perhaps doubling boost sounds more impressive than 25% increase...shrug

What car/year was that plot from? That blue line barely passes 10psi, I can do that all day long not even close to redline.

Stock boost is a joke. Max I've seen on stock tune was 11PSI.
