I have a S3 engine in my A4 avant with front mount intercooler and stage 1. Still running standard exhaust system (noticeably small).
There's a lack of aftermarket exhausts out there for the b7 so thought I would try a free mod - removing the pre cat which is straight after the turbine housing...
Nice spec
I have a b7 avant Quattro with BHZ engine k04
So we're almost the same :)
However I haven't got HPFP yet and still running standard tiny restrictive downpipe.
Where u getting it mapped ?
It will be night and day compared to a standard car
I think you will struggle to get pinned back to the seat feeling from these engines as the power delivery is very linear compared to older turbo cars where it was nothing...........boooooooosssstttt!
I have a turbo kit for the tfsi engine available if interested.
I was planning on fitting it to mine but I need to buy a trailer for my track car instead
It's a TD05 20g will flow enough for 400bhp easily
