Does this look like a healthy RS4? Stock apart from Caf and K&N panel filter.

If you have a browse through the thread Rick put up earlier it looks like you could be somewhere around 400bhp based on Ricks first post which was at 160g/s per bank

Yep, im getting 320 both banks easily but I'm modified and no carbon clean. I've hit high 340s before.
The man maths is that the sum of both banks i.e 1 bank doubled equals about 80% of Max power so as stated above, a combined Maf of 320 is equal to approx 400bhp.

[JmRS4]

That's not too bad then. It's got the engine management light up still something to do with cooling fan which Rick_RS4 reckons it's the module and one about the secondary air pump having insufficient flow?
I'll have to get manifold off and see if it needs carbon cleaning.

[MikeFish]

Unless it has been carbon cleaned in the last few months it will 'need' carbon cleaning.

[MikeFish]

FYI, 160g/s is a pretty good reading for your car given the mods you described assuming it hasn't just been cleaned.

[JmRS4]

I don't think it's been cleaned, I've only just bought it so not 100%. Noticed a difference after fitting the caf mod.

[JmRS4]

It hasn't been carbon cleaned, done 41000 miles.
