Turning off auto stop kills deactivation but I didn't know that till today. A little extra throttle solved it too though.
On the flip side fuel economy was great - I averaged a reported 8.5L/100km despite not being particularly gentle on the throttle. My brick of a RDX is lucky to get 10.5L/100km the highway.
Side note: I've never felt as poor as when I talked to the sales guy. They're dealing with 8 (and 9) figure net worths and telling me about the Dr who already owns 6 Porsches who had to fight to get a $400k GT3 and here I am waiting for a tech IPO to write the cheque I need to buy a GTS. My 1% problem, LOL.

I also have the auto start/stop + cylinder deactivation on my GT4. I always just turn it off the moment I step into the car. In addition to that too, even with the sport exhaust on (valves open), they are not always open. When you have it on, The valves will open during idle and anything above 4-5k depending on what gear you are in. However, they stay closed during 1.5k to 4k rpm.
