Great information...you guys have brought up some good points. Just what I hoped for!

I have the Touring trim package with nav. Also, aren't the convertibles heavier than coupes to begin with? I ran with 20's that are both wider and heavier than my stock wheels.

Supposedly the stock ECU can adjust AF to compensate for the exhaust but I wonder if the headers, intake, and manifold have leaned the car out more than the ECU can compensate. The car has not been tuned or flashed since the stuff was bolted on so there is undoubtedly some untapped performance there.

Will get a dyno run before my next mod to see where I am at the wheel.
