Hey Guys,
Just thought I would post an update on the EA888 Gen3b engines.
I have a VW tiguan 2021 with the Ea888 gen3b 190HP version. I know people are scared to tune this beyond stage 1 due to the high-compression nature of this engine, but it is possible. Provided your tuner knows what he is doing. Obviously it might run down the life of the engine, but I am okay with it as I like to enjoy my cars when I have them.
Speaking to my local tuner in India, Hyderabad, he mentioned that he did tune a previous Q2 with the same engine to 380HP. All it needed upgraded was a downpipe, IS38 turbo, intercooler, Plugs, coil packs TCU tune and ECU tune.
So I pulled the plug and got mine done. It is all good and running fine after the tune and he claims he should be pushing around 350-360 Hp and over the next few weeks we plan on bumping up the boost slowly to achieve 380+ HP if possible.
Now to the car itself. The fastest car I ever drove setting aside supercars on hire is my daily drive EQC400 which is pretty quick with a 0-100 time of 5 seconds. My tiguan now is definitely pushing way above that and it keeps on pulling all way up in the rev range to 200 KMPH. it is a blast to drive and quite scary the way it pulls when the boost kicks in. It is running a 95 ron map. Testing the possibilities of doing a 100ron map which should ideally give more power and torque.
I saw this video where a tuner successfully tuned it and got 390 hp out of this engine. This gave me some confidence along with my tuner stating that he has done it before.
