Got the Zed tuned today at Z1. It's a 2011 Touring model with a 7 speed auto. I have K&N drop-ins, test pipes with 400 cell Magnaflow HFCs hooked up to the Garageline midpipe flowing out to some loud Beluga axle backs that drone a bit. Baseline with those mods was 292whp/241wtq. After the tune, I had 314whp and 262wtq. What I saw on the graph on the video looked pretty flat for torque. The stock exhaust was 1.75 inches feeding into the Y pipe and 2.25 inches at the largest so there was a definite improvement in flow over the stock skinny pipes evidenced by the baseline being nearly 300 already.
