Wow, what can I say other then mind-blowingly fast and almost scary. Spoke with RaceChip support today and had my GTS Black chip updated to max performance. Put Octane 101 in the tank and on Race mode the car pulled so hard at 15mph that it felt like it started to swerve, but maybe I was losing traction, but accelerating so hard I didn't dare take my eyes off the road while I pulled onto the freeway. Crazy part is that I didn't even have the XLR chip enabled. With that enabled on R+ this thing would be even a wilder beast. Can't wait to see my times on the drag strip at Sonoma this Wed. Looks like the weather will hold-up therefore should be good to go. I will share my times. I think I will do one pull with Launch Control (XLR should matter for this, but I will enable it), another pull with Auto-hold on and R+ on the XLR, not sure about Traction/Stability control and then depending upon how those go, I might do a third run with the chip disabled for comparison. If you have any suggestions or feedback, please share. Needless to the say the chip will be in Race mode. I still want to get my car dynoed. I will share those results as well. I won't be surprised if I'm getting at least 400 whp, but we shall see. With as much power and torque as I feel now, I couldn't imagine any more. It's border line safe to drive as is, but what a blast. Just on the verge of insanity.
