Jetta 118 Tsi - underground performance stage 1

[pocketpunch]

Hi team,

I'm back with a review of sorts.
I contacted Alex from Underground Performance on their Facebook page the other day and organised they do a simple stage 1 tune on the mk6 Jetta - Manual Transmission.

After an initial obd read, the map took about 25 minutes to be generated followed by you driving your car with Alex to log some data.

Now - to the juicy part.
I was charged $775 for the tune which puts it down to a great deal since its a custom written tune with your specific car in mind.
They look at the engines reaction to being subject to higher outputs and see if any problems can rise.
They prefer to make their power through fuelling and ignition optimisation rather than just ramping up the boost.

Anyway,

The car is incredible now.
It really feels like this is how it should have been from factory.
The pedal is now a linear input not that factory delayed response you get from the stock car.
The engine is really snappy to your inputs and the power delivery is savage.
The low end mostly feels the same but the car will now pull like a Mo#######er after 3000 Rpm.
It generates power to redline and doesn't bog out like the stock car did.

Haven't done a dyno, but we're definitely sitting on 200 Hp as this feels like a stock Gti now.

Only mods I've done was a dv+ and the plastic airbox grille delete.

Guys, seriously urge a good custom tune for the twinchargers - for those of you who have the latest generation of the engine ofcourse.

I'll record a few videos demonstrating the cars acceleration and post.

Any questions, fire away.
