The last analogue fast A4
Nothing after it sounds like a B7 RS4 at 8,000rpm. This generation rewards a different kind of tuning: the 2.0 TFSI cars take boost like their Golf cousins, but the V8s are about breathing, response and the chassis - intake and exhaust for the noise and a modest gain, then suspension to replace the ageing (and failure-prone) DRC dampers. Add the service parts that keep FSI engines healthy and a B7 becomes a car you keep forever.
The proven upgrade path
B7 - frequently asked
How much power can the RS4 gain?
Honestly: 15-25hp from intake, exhaust and a careful map - it's naturally aspirated and already highly strung. The transformation is in response, sound and the chassis, not the dyno sheet.
What's DRC and should I worry?
Audi's Dynamic Ride Control - linked hydraulic dampers on S4/RS4 that commonly leak with age. A coilover conversion is the standard fix and improves body control outright.
Can the A4 2.0T really make 300hp?
Yes - it's the EA113 family, so the Golf GTI's K04 conversion applies: turbo, fuelling, intercooler and a proper map. A quattro sleeper for sensible money.
Do you offer ECU tuning in-house?
Yes - Stage 1-3 and custom ECU mapping are done fully in-house. We don't currently offer parts fitting, but we're happy to advise on your install.
