The Europipe Stage 2 exhausts, with larger diabeter tubing and less restrictive CATS (100 cell) provide freer flowing exhaust. Therefore the engine has to work less to get the turbos spinning. They claim boost comes on around 500 RPM sooner. As well there is an increase in peak power.

GT2 or X50 programs are not the same as Stage II... the Stage II setup is more aggressive. I started with the GT2 program as a baseline and it was still too lean. We had to revise the software 4 times to get it right. I could still tweak it some more, but im running 1.1-1.2 bar with solid AFR.

I will say that when it's super cold out, I can exceed 1.3 bar and run into limp mode (cold crisp air will do that)...but that probably has a lot to do with me fooling around with the wastegates.

The has been running strong without any issues.
