Chipping my Q4 and waterspray question

standard pressure is 2.5 bar masured vacuum hose of engine ideling!

Thanks for clarification, I thought it needed mentioning.

2.5 you say? Do you think my Evo 2 was the same when standard? It's chipped and reads 3 bar now and I was led to believe it always was, but not so sure.

Yes the standard pressure is 2.5bar , then for your commentaries i see that the best recommendation will be to raise it to 3 bars, isn't it? :smile:

"The only way to be certain is to check your AFR, anything else and you are just playing a dangerous guessing game."

Uuuuups sorry Evodelta, It's true, you said it before, but I have a problem, what is the AFR? excuse me for my ignorance :doh:

I believe it is Air Fuel Ratio: http://en.wikipedia.org/wiki/Air-fuel_ratio
