Does anyone notice a hesitation when the new-style 5.3 changes from V4 mode to V8 mode?? I thought that this new technology was supposed to have a seamless transition from 4 to 8, but mine doesn't..in fact, I'll give it a little throttle to speed up a little, and it'll actually surge out from under me, making me hit the brakes. I love the car otherwise, but this is becoming a nuisance...any info, anyone??
