The 16 valve engine's turbo is not a bolt on due to the manifold differences between the 8 valve head and the 16 valve head, hence why the CHRA is placed in the PD140.

The GTB1749vc has a slightly larger turbine wheel and compressor wheel than the GTB1646v.
Well, that makes a lot more sense, and clears up my confusion! Thanks

That might be the vacuum line coming from the EGR cooler. I'm not 100 percent sure because my EGR cooler magically fell off before I bought the car. If you deleted the EGR, then you'll need to plug the vacuum port that line would connect to. Below is an easy to follow vacuum diagram for our cars that sptsailing made.

Also, do you have VCDS? It'd be interesting to see what the full readout shows.

Yeah, it looks like the hose that runs from #12 to #9

Still have the EGR (California)

I do have VCDS. The only codes I see for the engine are the smart actuator and cam sensor. The tune will take care of the actuator. I'm sure if the egr is supposed to have a hose connected it will pop up a code soon too. If you want the whole VCDS dump I can paste it here.

Wont be able to do anything more until I get off work. Will update later today

I've been considering replacing all the vacuum lines, in my car, due to some of them having been hodgepodged together, and making me get under the hood and clean everything up, and do a "wire tuck" job on it. That schematic is awesome.

IT RUNS!

figured out the cam sensor. Torsion value was way off. Adjusted it little at a time until it started. Read the value and it was -6.something. surprised because I thought anything more than +/-5 it wouldn't start unless unplugged. Mine started with more then -6.

Anyways, adjusted it to 0.5

Starts and idles good. Broke in the new cam and took it for a test drive. First impression, feels like twice the power. There are a few spots where it feels like a dead peddle or major turbo lag, looks to smoke more then I would like right now but hard to tell because it is night and judging smoke in headlights behind me is very deceiving. Overall way better then stock. Sent a log to Malone. Will see how it is after some tweaks

Keep you updated

Good deal! Sounds like you had a pretty smooth install and a good running car. Getting the engine to land above 1800 RPM on the gear change will allow you to stay on top of the turbo when you need the power, it should hit like a light switch above 2k.

Yes, there is a point where it seems to wake up. I will have to study it behavior and learn the best times to shift. Of course it is a DSG car so manually shifting is not always practical. I may need a DSG tune update to accommodate the new power band

Mine is also a DSG. Sport mode works very well for the time being. When using drive you need to be a bit aggressive with the throttle to keep it from upshifting too soon. When getting on it in sport mode it pulls like a train to 4500 rpm. Applying a DSG adaption with VCDS may also help.

Played around with the torsion value (cam timing) to see if i can smooth out the idle more.

Adjusted it from -4.4 all the way up to +8.2 in small increments. Starts to smooth out around +3. Left it at +3.4

Also, I ordered a DSG tune update. Hopefully this will take car of the over rev neutral problem

Still waiting for an updated version of my tune based on the logs sent. Stay tuned

Got my 1st version of the DSG tune uploaded

1st impression, it certainly wakes up the responsiveness of the throttle. Revs quicker and thus builds boost faster. Much better driving manners. No real need to shift manually now.

Sport mode still needs to be addressed as it shifts way to high and hits the rev limiter

So far so good

Glad to hear it's going well! I'd like to see a video if you can do so safely. I'm curious if my car has a DSG tune or not, since it came with an EGR delete and stage 1 tune.

I'll see if I can get a video. What do you want, a shot of the cluster? From a stop to 60? 45ish to more?

Maybe I can get all. We will see.

A shot of the cluster would be perfect, I'll show you mine if you show me yours. Acceleration to the speed limit and deceleration in sports mode would be cool to see how the downshifting is. My 2010 would engine brake on its own and downshift, the DSG in my '06 is nowhere near as intelligent.
