Yes, that is the way it is supposed to work. Porsche created this image, IMO, because geeks like us would pass it around when this subject came up.
To the OP: DFI engine is no small change. It is a totally new block. I also know from replacing the shocks in my 2009 C2S there are suspension differences. Nobody seemed to write about them but the car configuration in the rears is different. Did Porsche do this to fit the new engine or did they improve the system? I dunno, but there are more substantive differences than just the block.

they revised the entire suspension layout on the 997.2 cars.. I watched a video somewhere where they had them both on a lift and a Porsche engineer was explaining how they upgraded the control arms hubs and shock mounts.
I think it was a product overview class for Porsche dealerships service center.
In a nut shell the 997.2 has a complete powertrain and suspension package revision from the 997.1. It also has an interior and PCM upgrade.
Very big differences just on the engineering side not on the cosmetic side..
I like to think of it as part 997.1 and part 991.1

This reads like someone talking to you while walking away from you and then coming back and finishing their thought. You're not going to uncover some National Treasure type secret in the 997.2 that hasn't already been discussed for the past EIGHT YEARS since its been out.

Except for early 2005, the IMS is not an issue. I have not spent any time in a 997.1. Went from a 996.1 six speed to a 997.2 PDK. Both C4 cabs. And honestly can't tell a difference in speed. No track time, just driving. The place I can tell a difference is the gas pump. Much better mileage in the 997.2-if that's important to you. I drive a lot so I spend less time at the gas station.

The mechanical changes are more significant.

One downside to any DFI engine is carbon build up that traditional fuel injected engines don't suffer.
Many if not all DFI engines will have to have that crud cleaned out. Some need it every 15K miles, like some Audi cars I've seen. Others, it could take far longer. It's seldom talked about, and it's not cheap. With Porsche and it's usual pricing, I would expect this will be a costly expense when that times comes.

You listed all the major changes, and they are major. But you dismissed them. And then want to know what you are missing. Perspective I'd say. To me it sounds like you are just trying to convince yourself that your 997.1 is just as good. Not saying it's not, but the improvements made do matter to a lot of people. Especially the audio/nav system.
Much as it pains me to say, I'm with quadcammer I think lol

Facts are so helpful... how we each react, when faced with them, that's another matter.

The old cliche "Get the newest Porsche you can afford" holds true for the 997.1 vs 997.2.
If you can swing it get a 997.2. If you are like me and value bang for the buck get the 997.1 and get a thorough inspection first. My car has had its engine replaced for bore scoring (before I owned it). The engine is still under warranty until May 2016 so I drive it as much as I can to try and shake out problems but I haven't found any. I also change the oil every 3k miles and send a sample to Blackstone for analysis. I've done it twice and the first time the results were consistent for a brand new engine that was breaking in, the second time it showed near perfect results.
Pricing for 997's are over the place and I think a lot of private sellers have unrealistic expectations since there is so much inventory available. Good luck and take your time....and maybe take a test drive in that 911 you sat in before going crazy.

I wonder how good the suspension refinements could be if they are not even listed (in the PDF document) as an improvement among the list of "New for 2009" features.
New for 2009
Though the 2009 911 Carrera and Carrera S Coupes boast several important
refinements over the 2008 cars, the cars carry the same internal 997 designation as
their immediate predecessors. Chief among those refinements are new, more
powerful and fuel-efficient engines and the availability of Porsche's seven-speed
double-clutch transmission, the PDK, in place of the optional Tiptronic S.
Other critical changes include larger, more potent brakes, a revised Porsche
Communication Management system with Bluetooth connectivity and available voice
commands, a fresh exterior with BI-XENON™ headlights, and light-emitting-diode rear
lighting.

On a 997.2 C4S you get electronic AWD - same as turbo 997.1, 997.2, and the 991.1.
The viscous clutch system awd was used on the 997.1
The 997.2 Carrera 4 and 4s therefore has "significantly" different suspension and drivetrain layout than its 997.1 predessor. 997.2 4s also comes with a standard mechanical diff.
It wasn't until the 991.2 that electronic awd unit is now paired with optional rear steering and electronic rear diff.

This is quite simple really.
Yes the .2 is overall "better" than .1, and the 991.1 is even better...just like allmost all upgrades since 1948...
I prefer the .1 look over the .2, and the price difference then made is possible to get an even better spec on .1 car over .2. Winwin for me.
Same on my 356, the C is the best car, got the BT5, as it has the look I like the most.
If you want the "best" piece of technology buy the newst car. I you want the car you like, then... Well...
