[Angrybird 12]

I finally got mine installed. So here is my take. Remember this is on a 2012 LFX V6 Automatic Convertible. The convertible will weigh more than the coupe so the effects may not be as dramatic in some cases. For mine I say forget anything under SP3 because you won't notice much change. SP4-6 you get quicker downshifts ( both normal and sport modes)and when making a turn pulling out you need to be careful because for the first time on dry pavement pulling out the rear end broke loose and I fishtailed for a good 100 ft. with TC off, with TC on it was kicking in a lot more than I am used to. On 7 I got wheelspin pulling out in a straight line. On 8 and 9 I think it's too sensitive for street use. The transmission was kicking down to a lower gear with the slightest application of the throttle. If I used them on the street I would probably use manual mode.
My instructions still indicate EC mode is not supported with our cars so I did not try it.
My normal setting will be SP3 or 4.
