Someone could tell me his opionin about the MOD map of this car ?

Is there a solution to close EGR valve ?

Someone could close it ?

Is it possible to improve this map ? where ? Is it a good map for a GPL engine ?

Is there a better map than this ?

Tank you so much

How much bhp did you gain on the rolling road?
What's the CO-level (before the cat) or the lambda number with WOT?

I never tryed on rolling road. The mod map is better than original but I don't know if this map il the best.

How can I read the CO value from oxygen sensor ? By vag com ? wich address ?

Could you improve this map ?

Could you close EGR valve by map ? by vag ?

thank you so much

If you didn't use a rolling road and didn't measure the CO percentage, the odds are this map produces less power than the original one and could damage the engine.
And if I could make the map better? Assuming it is possible starting from an original map, only on a rolling road and with at least CO measurement. But I doubt there are big gains here. Maybe, if you are very lucky 2 or 3 bhp.

Thank you for your answer.
I know that with this engine the gain is low, I asked this becouse I hoped that you (or someone) made this tuned car before, and now could give me some opinion.
