91 Octane

mid throttle surge.

Laggy Launch and No 2nd to 1st kickdown. Transmission feels ok. When flooring it in 2nd gear, it will not kickdown to 1st even if 2nd gear is at 1000 RPM.

stock turbo, cobb stg0 280hp yet they say it cant be done. But the math don't lie

The car is all stock except for an exhaust behind the cat, NGK Racing spark plugs, Delicious Tuning ignition coils, and of course the Edelbrock supercharger. Currently the ECU has the "CARB" tune that Edelbrock includes with their supercharger kit. My main concern is to know if it is running rich or lean (you said it was running rich last time) as I am most concerned about the longevity of the engine. Also, when I push in the clutch the idle will go up to 2k RPM for a few seconds then settle back down and sometimes bounce around a little.
