few pics of my new purchase

Any way of connecting a pc or tablet to see how much air its sucking in? That'll give you a good idea of any power loss problems without a dyno.

Tell me more about this please Mike....

When I got mine it was a bit of a let down have to keep the revs high, if I had not got mine Supercharged I would have sold it and gone for a RS6 C6 I think

Apparently you can work out approximate horsepower of an engine from the amount of air it is using.
It's been said that the amount of air (measured in g/s) should be about 80% of the horsepower, e.g. a 400bhp car should be using 320g/s of air.
So a standard RS4 with factory power should use about 331g/s (414 x 0..

I measured my car and it hit about 350g/s when giving it some beans, so 350 / 0.8 = 437.5 which is about right for my mods.
I measured mine using a bluetooth OBDII adapter connected to a tablet runnig the Torque OBD app which reports the air for both banks. I believe VCDS reports each bank individually so you'd need to double the air intake values to work out the power.
