From TSI to GTI

[Lucas_R]

Does that mean DNA "upgrade" boost power at higher revs at the expense of torque below 2600 and so diminishes the responsiveness of the stock engine at 1500 RPM?

No loss of low down power - simply more power everywhere and for longer.

Turbo boost actually comes on slightly earlier and harder too.

And the advanced ignition timing will also help boost the engines responsivness.

there is no power loss at all with the tune. It makes 220nm from 2600rpm, whilst been progressive from the stock tune of 175nm.

So stock is

1500-175nm
2000-175nm
2500-175nm
>4100rpm

Where the tune is

1500-175nm
2000-190nm~
2500-210nm~
2600-220nm
>3600rpm

So overall a stronger middle power band and the same stock starting grunt.

A - Low ks, so far I love the DSG but I rarely drive in stop start traffic.

Okay thank you. I was only apprehending some impact on low-end torque not kw.

Anyway, the only other question in the cost-benefit analysis would be what are the downsides or risks, if any, associated with the upgrade and how and where is it done.

Is fuel economy adversely affected? Mine is used mostly for short - medium inner suburban driving and averages around 7.8l/100.

Is fuel economy negatively impacted to a greater extent depending on type of driving?

Are there risks to any part of the engine or drive train?

How is the procedure reversed? Complete reversal possible?

Oil consumption same?

Thanks in anticipation.

The software file on the engines ECU is overwritten with a modified file. The modified file changes the boost/timing/fueling etc etc to produce more power.

Fuel economy is largely unaffected - in my case, my economy is actually better than stock and have gone from 188kw up to approx 250kw. Mind you, if you drive like a bat out of hell all the time you will use more fuel.

The tunes are developed to push the boost the engines power safely. Stock ECU tunes are setup very conservatively to cover for bad fuel, lack of servicing, lack of mechanical sympathy etc etc.

Procedure can be reversed by re-flashing your stock software back onto the ECU.

Thanks, Lucas.

I presume 100kw is okay with the standard TSI suspension and brakes.

Thanks, Lucas.

Unless you are driving at 200kph down the freeway then yes. I only have different brake pads (low dust pads) in my car and ive never had an issue with brakes, even when having some fun.

It should also be noted that most of the tunes would require you to use 98Ron fuel as the tolerance for lower quality fuels on the stock map has been overidden.

Usually standard equipment is fine for stage 1 tune, i am using standard on stage 2 (other than my preference in brake fluid) and it is still fine.

He is based in Melbourne so you could shoot him an email and ask to organise a time to do it.

All the tunes are developed in the UK by tuning guru John Robins. Theres quite a few 77TSI owners on here (mostly Polo guys) who have the DNA tune too.

Awesome! Thanks man
Could you pm me his email address?
