What do you mean by modified OEM intake? Eventuri anygood or no need as long as you have a wider TIP and elbow?There is a lot of cheaper options to run Stage 3 car around 500HP than APR. Also this kit on previous post is not for EA888 Engines...
You need:
- Downpipe
- Intercooler
- Modified OEM intake
- Hybrid IS38 Turbo
- ECU Remap
- DSG Remap or if you have manual Clutch which will handle power/torque
This are minimal requirements to run around 500HP then you can add HPFP, LPFP, WMI ...
That is debatable. Some tuners change it on 450+ some go up to 500 on stock one.
As tuners post on forums around 450-460hp you can start noticing loss of fuel pressure.
I am not tuner so no idea how much it is justified or just a security measure so it does not get lean.
I also read some posts were folks killed 2.0 tsi.engines when their fuel level was low and engine suddenly lost fuel pressure while hard starts.
Definitely something to it but let's say debatable.
Some run 500hp no issues some cannot pass 460 on stock one.
It can only make a positive change.
If you have time see vwroc forum.
Lots of 500hp+ cars run it as a safety precaution.
Still this is 400 price tag level mod so something to consider budget wise.
