Installed the Hamann. Sounds ridiculous.
However...
My butt dyno noticed a 25-50% decrease in hp and torque! When in sport mode, halfway throttle would pull hard. But now it feels like it's struggling. I put the Sport Display to track hp and torque and it "seems" less than before.
I also have a Dinan Stage 1 Tune.
Not sure what's going on. Any ideas or is it just in my head?
