Do I have REVO or boost leak?

[sekenzo]

I bought an A3 1.8T AGU that is suppose to have REVO stage one remap, but i can't be sure. Can anyone tell me what is the best way to determine that the REVO is there?

I did a vagcom log on block 002 and the highest maf reading is 135 at 6300rpm. Looks a bit low for remap car? Could it be a boost leak or just running on stock with no REVO?

Take to a local REVO dealer and get them to look. Then can probably use an SPS switch to test.

I had a similar issue to you with my REVO stage 1 ECU being down on power. Turned out to be the MAF. Interestingly it didn't put any VAG fault codes up - it was just screwed.

Then again, MAF readings of 135 make your engine somewhere around 165-170 BHP....

so you reckon I am chipped but there is a lost of power somewhere? What is the quickest way to check for leaks?

Get someone to do a pressure test on the system mate to be honest is the best way. There are methods of doing it yourself, but I would get it properly checked out.

As a matter of course, check the PCV hose - this is a common point of failure!

Thanks. Can you give a bit more detail on which hose and a recommended place / link to it?

Here is a link to a post discussing this hose.... I would take pics but it's dark. It's an 's' ish sort of shaped hose the comes out of the bottom of the inlet manifold. You will be able to see it when you look for it.

No.... I'm afraid not.
