Dialed in another 5% boost to throttle sensitivity (10% total) and I think that I'll keep it there for awhile. There is a marked difference in throttle response, enough so that I have to "relearn" my foot to pedal coordination with this car again. It's not THAT much of a difference, but it has changed enough that I have to be cognizant of what I'm doing with the pedals. If I goose her, she goes; no hesitation. She also backs down almost instantly, and purrs like a (mean) kitten when she does. I'm happy with the tune and the throttle adjustments. Once Eric gets his hands on the software to enable a custom tune for my car, I will do that. BTW, I mentioned to him that some of you all might be interested in a custom tune since most of you have the '09 and '10 cars. He's standing by to hear from you if you are interested. You won't be disappointed! brooksspeed dot com.
