Had the broken TEE behind manifold so I pulled it all out and put the solid Tee in place and fixed all the vacuum lines. CTT started right up and ran perfect! An hour latter had a little rough idle but now its cleared up, a slight hesitation now and then. No lines broken, loose.
Now I have codes P2225 and P2227 throwing a code, still runs pretty good.
Battery is brand new.
Any ideas?
Thanks

What are you using to read codes? The only one of those that’s in the official Porsche diagnosis manual is P2227 which is for the ambient pressure sensor in the DME. Erase them and go for a nice long drive and see what comes back. I have seen cars that have been running with a vacuum leak for a long time throw odd codes after they get fixed. I would also recommend a throttle adaptation.
Thanks PTEC. I'm using a Durametric Pro. Just did the throttle adaptation through the Durametric. Still sounds a little off. Will drive it and see. May have to do a smoke test.
I agree, I'm looking at the vacuum connections. I also bought a new MAP, mine didn't look the best. Not that I know any different. Will post when I sort it out.

MAP Sensor, throttle Y pipe. Manifold Absolute Pressure
To be fully accurate that is not a map sensor, thats is just a boost pressure sensor. Your cayenne uses 2 MAF sensors to measure air flow, not a map sensor. A map sensor would have to be behind the throttle valve.
Yes correct upstream of the throttle body in the Y Pipe. Bosch Part Number is 0 261 230 042, measuring boost pressure. I don't think that is actually a problem, mine just looks squirrely.
I have not yet gotten to the 2 MAF sensor on each side.
FYI: The "Y" pipe is notorious for leaking at the seams and it may be your problem. Don't you love Porsche's cheapness on materials?
Are you talking about the Y intake plenum at the front of a turbo motor? My 26,000 mile one is sitting in a box since I installed an ipd one if someone wants to buy it for half of a new one?.
Yes. The "Y pipe" is considered cheap by Porsche standards. I replaced mine at 50k miles for piece of mind. Pretty sure it was around $50 when I bought it 3 years ago. Porsche probably buys these for less than $1.00 each.
