This thread was last posted 3 months ago they found the problems with many of the cars was due to a glitch in ecm where the cars were filled with 87 octane gas by dealer and the computer pulled back the timing. The cars SHOULD have adjusted things as 93 octane gas was used over time but didn't. A fix was found in removing two fuses and waiting a few hours for the ECM to clear then reinstalling them. Most people felt a sizeable improvement from their underperforming cars. Check the stickies for more details.
