I received back and installed the Fabspeed Tuned ECU file and had a chance to drive the car about 100 miles on all types of roads yesterday - WOW!
The car runs great and fast. It feels more responsive and stronger pretty much everywhere, like a Cayenne Turbo S+ and I haven't noticed any odd behavior, monitoring AFR, boost, etc. The result is that this thing is just a beast now - thinking it could give my supercharged 911 a run for it's money in 80% of the situations - something this big just shouldn't move like this and the sounds are sublime - not too much of anything (intake noise, exhaust noise, blowoff sounds, etc) - just the right amount of all of it.
Thank you for the info!!!
A question i forgot to ask originally is... if there is about 1.5" offset between the front and the back, without the center coupling doesn't it put extra load/flex at each end where driveshaft is connected?

It has a joint (like a CV joint) at one side that allows it to rotate freely even though its not in a straight line and has to also be able to do this to adjust for suspension settings and load levels.

A few pics from today now that the car is off the lift and sitting on the floor - these at loading height.
On the PCCB brakes upgrade, I've decided to order the 957 rear calipers that have the axial mounting holes to overcome the issue where the PCCB rotors and the stock rotors are about the same size and the radial holes through the yellow calipers and the axial holes through the red calipers are in about the same place, making it very difficult to have an adapter made. The PCCB rear rotors have the same part # in PET for both the 957 and 958 generation so the rotors I have should work fine, and since they're the expensive part, it made sense to just change to the proper calipers and I'll sell the rear 958 PCCB calipers in the Marketplace or on eBay. I'll have both the 957 and 958 pads on-hand in case they aren't the same. For the fronts, I've just sent photos and measurements off to Epytec in Germany to start the process of having the adapters manufactured to use the 958 Front calipers and rotors on my 957, but that will probably take a few weeks.
From the oil change I did on 4/23, I got the UOA back from Blackstone today. I have no idea what make, grade, or weight of oil was in the car as it's what came in there when I bought it before starting the widebody project. I put only 2,800 miles on it, but had been in there since April 2016 and before driving it more regularly and harder, wanted to start fresh. I was glad to see that things looked pretty good with respect to the TAN & TBN and the Zinc & Phosphorous levels were up near 1,000 PPM which is what I like to see for the valve train. This is not the oil I'll be using long term as aluminum, iron, & copper levels are at least a couple points higher than I see in my other Porsche motors, but still within the acceptable range for this blind sample

I also took the car on it's first real road trip today - 2.5 hours. It performed flawlessly with the cruise set in the upper 80s and AFR, Coolant Temps, Intake Air Temps, Boost, etc all looked perfect. I was looking at intake air temps to see what kind of difference from the ambient air temp I was seeing with the HHR intake since they're positioned above, but slightly behind the larger FVD intercoolers. On the highway, they were only 7-10 degrees F higher, which I think is fine and probably not much different than I'd see from the factory airboxes. In traffic they were a bit higher, but not worried about that much since that's not when I'm looking to make power.
Prior to the trip today, I also added Bluetooth streaming audio to work alongside the inherent BT functionality for phone calls. PCM is connected as the phone source and BT receiver as the media source plugged into the AUX jack in the console with the goal being to stream Pandora and Waze info and have handsfree call capability, like I do in my other vehicles.
Bought this from Amazon Mpow Bluetooth Receiver Transmitter, 2-in-1 Wireless Bluetooth Adapter, Bluetooth Receiver for Car Home Stereo System to Enjoy Music，Bluetooth Transmitter for Enjoyiny Night TV Show (A2DP/AVRCP)
charged it up and plugged it into the USB port for charging and the AUX port, paired it with the phone, and wallah - works perfectly (just have to power it on each time you get in the car and it automatically connects as the media source).
I also lubricated the Pano roof tracks and pivot points with a Teflon Dry Spray Lubricant and treated all the door and roof seals with Gummi Pflege. Roof moves smoother and faster now.
Also, the Atturo AZ850 tires seem just fine. Good cornering grip on the onramps, offramps, and under full throttle overtaking and a smooth ride. I'm actually a bit surprised how good the ride is since I'm running a 22" wheel with a 30 aspect ratio tire at Sport ride height and Normal chassis mode - very smooth and compliant, not harsh at all. When the road surface gets worse, a push of the Comfort button takes care of it and when I want things tighter, a push of the Sport Button does that. What's leff to test on these is wet weather performance and over time the tread life, but with a 315 section width and 12" wide wheel, I'm actually expecting some faster wear - as long as it's even, I'm OK with that as these tires are very reasonably priced with good speed, load, traction, temperature, & treadwear #s.
Returned from the weekend away soccer tournament... the drive home was as awesome as the drive there, but the car was nasty, so had to wash of the bugs and bird crap before I felt right about tucking her back into her spot.
Parking at the tourney this morning was a zoo - popped it into Special terrain mode and climbed up the curb to a nice, safe spot. Even the low bodywork wasn't anywhere near the curb in that mode.

which consists of a metal ball base and then a magnetic receiver that attaches to the back of your phone. Since I have bases in all of my cars already and the concave magnetic receiver on my phone, now that I have the Cayenne back, needed to make it compatible for trips. The problem was, I couldn't find a good location onto which I could adhere one of these bases that: A) wouldn't be in the way of something, or B) wouldn't cause damage to whatever I stuck it to upon removal.
What I ended up doing was sourcing a threaded 1" ferrous ball from www.bearingballs.com and purchasing just the mounting bracket from Rennline's Cayenne phone mount kit, then using a 1/4-20 bolt with a 3/4" spacer threaded into the ball. The Rennline bracket is a great design as you pop off the PCM surround trim, and it wedges into the gap between the leather console and the trim, using the 2 left PCM attachment screws to hold is securely in place. It can also be mounted on either the left side or the right side.
Before installing the bracket (for clearance reasons) I put a lock-washer on the bolt, then threaded the bolt through the bracket, then slipped on the spacer, and threaded on the ball until tight, then installed the bracket into the console.
Works Perfectly - doesn't block any of the controls, if far enough from the control stalks on the right side of the wheel to not have any interference and is in plain view for ease of use with Pandora & Waze while driving. I have an app on my phone that let's me force 180 degree screen rotation so it can be mounted inverted and work normally. If you mount the magnetic receive in the middle of the phone, it wants to spin when you drive and hit bumps, and you can't place it at the top of the phone since on an LG that's where the camera lens, power button, & fingerprint reader are - so you mount it at the bottom and just the phone upside down. The Steelie mount for the phone has a rubber section in the center that helps it grip to the ball and not rotate too.

I'm very pleased with the result !
Hey Pete,
Very glad to hear you are enjoying the tune! You've built quite the Cayenne and I'm excited that the tune could help pull everything together and see its true potential
Feel free to give me a shout if you ever need anything!
