Hi everyone, just an observasion ... I am not one who uses the "auto" climate control so it is always on in some way or another, I prefer to simply turn my climate controls on or off using that button. So it has cooled off a bit in North Texas so I have been driving around mainly with AC off. Typically, from the many prior cars Ive had, this results in a bit more performance as the AC can put a little strain on the engine from the compressor being on. My RS400 is noticably less responsive and seems to shift much earlier with the AC off than it does when the AC is on!!! Anyone else notice this? The difference is VERY obvious. I turned the AC on this past weekend and sure enough the car was so much more responsive and aggressive and held gears a bit longer. Is this intentional by Infiniti since they figured most folks would always be using "auto" climate control which from what Ive read on the forums seems to keep the AC compressor on at all times? It is the only car Ive ever had that is reverse of what typically happens when one turns the AC off in a performance car. Anyone?
