I noticed a few things things while driving the cars at last weekend's SRT-8 Experience in Fontana. First, none of them bumped the rev limiter during the first to second shift. Also, some cars would automatically upshift at redline when the transmission was in manual mode while others would bump the rev-limiter. I like that feature! One of the instructors said that the some of the cars recently had their programming upgraded. Hopefully the new tuning is released to everyone soon!
