Anyone yet figured out why the 2002 chip puts out 270 lb/ft while the 2001 chip puts out less?

Boost does not always equal tq and I am sorry but the 1.3 chip from Neuspeed is nothing special
over the GIAC and apr chips. If anything the Neuspeed has less power in the upper rpms.

Is there... perhaps... an upgrade for my GIAC chip? Since my 2001.5 has the lower compression...
... it should handle the higher boost better than, say, a 98 1.8T, no?

Which brings me to another question...
At the higher RPMs, it seems as if the wastegate is blowing open and dropping the boost. While this may be by design, is there a way around this with the stock K03? Is this controlled by the chip? And is changing the wastegate behavior something that people have looked into?
Longwinded, I know... but any thoughts are appreciated.

I don't see how you can say that there's not a direct relationship between boost and torque...
True, the neuspeed chips use variable boost pressure and therefore, aren't going to be running 1.3bar the entire time, but still... at max boost a 1.3 bar chip is going to out-muscle a 1.0 bar. Plus, that variable pressure mechanism is a good thing for the safety of a K03.

Technically there is, but there isn't...
in the case of the A4, the KO3 can only take so much boost in it's efficiency range. Boosting more will increase heat, which will thin the air, causing the turbo to work even harder. It's not that the 1.3Bar will hurt the engine, it will hurt the turbo.
IE, the Subaru guys were actually posting quicker quarter mile times with 16PSI than 18PSI.
