Are you sure it wasn't a sort of placebo effect?
Yep, I didn't time the car, but I know my cars. It definately woke it up. Other threads have reported their cars "waking up", I just shortened the process. Note: I may have gotten the same result by horse beating it a few runs like my 4th gen SS, but I didn't have to on this one. I have rolled on the accelerating a few time over the last 100 miles or so with some what dis-appointing results. I rolled on the accelerator after the reset, and the car threw me right back in the seat like it should. Anyway, like I said. It may not work for anyone elses LS3. But it worked for me. I wouldn't have even tried it if I felt my car was running up to par.
