Best Mods For 2.0 TDi Tuning [Seat, Audi, VW, Skoda Tuning Guide] EA188 & EA189 Stage 1 & Stage 2 

This video is based on my experience with upgrading my 2.0 TDi I will provide an introduction and explanation of the typical mods people do on their 2.0 TDi, explain what they actually do for your performance and help you to build an upgrade strategy for your own 2.0 TDi project.
Please let me know which car and which engine version or year you have and it will help me prioritize the production list I have.
I also love to hear your experiences and tips, and fully understand that not everyone will agree with my cautious approach, if you would like to see more in depth explanations and complex discussions let me know, I can cover fuel injection phases and turbo spool profiles for example but decided to keep this video accessible to even newbies to the world of tuning and upgrades.
My A3 came with the PD engine a BKD to be precise and I found many mods didn't really do much or work as expected. I later updated the article as the engine was revised and VW group went over to A CR fuel system, so have also based this video on the EA188 & EA189 engines and much of this still applies to the later GEN3 & EVO engines, but because there were so many revisions and updates I will focus on the Gen 3 & the EA288 range in a future video as these require a slightly different approach due to the way they were designed and operate.
The 2.0 TDi came in many power levels and had 3 major revisions and this video will focus on the early PD and later CR revisions of this great diesel engine (Gen 1 & Gen 2 primarily).
The power levels varied from 105hp to 225hp but most were based on either the 170hp or 140hp version. Revisions were EA188 EA189 & EA288 and each generation improved on the previous ironing out the problems and issues which are detailed in the video • Common VW Audi Seat Sk...
I will focus on engine upgrades such as intakes, cold air feeds, camshafts, turbos and fuel system mods. Exhaust mods and DPF removal are also discussed in this video along with the possible drawbacks of these mods & upgrades on your 2.0 TDi engine.
This will contain tips for 2.0 Tdi Stage 1 mods and also 2.0 TDi stage 2 mods and upgrades, most of our viewers will be taking their 2.0 Tdi to stage 1 which is a simple upgrade path, stage 2 takes more money and investment but does offer larger power gains.
Tunes or remaps are the most effective mod for this engine releasing much more power and usually improving fuel economy (depending on your driving style of course.)
We will look at tuning these engines, the best upgrades and mods for them, including 2.0 TDi remapping, 2.0 TDi tunes, Camshafts, Intake mods and exhaust mods and turbo upgrades for the EA188 EA189 & The later EA288 engines will be covered in a future video, although the principles of tuning the earlier versions still applies to the more recent EA288 engines.
In this video we break down each mod and help you fully understand what to expect from it, and how the mod will help your performance (or hinder it).
I will also talk through some typical misconceptions and provide my usual unbiased advice for tuning, modifying and upgrading the VW Audi Group 2.0 TDI engines.
