Stage 2 takes the standard IS38 to its ceiling. Two things stand in the way of that on a standard car: intake temperatures and exhaust restriction. Sort both and the turbo will give you everything it has.
With an uprated front mount intercooler, a 3 inch sports cat or decat downpipe and an R600 intake fitted, a custom Stage 2 file puts the S3 at 385 to 410bhp and up to 430ft/lb. There is nothing left in the standard turbo beyond that, and the car is properly quick at that point.
Don't skip the intercooler. The standard one heat soaks quickly on a warm day or across back to back runs, and once it does you lose both power and consistency. The downpipe lets the turbo spool freely and hold boost at the top end, and it's where most of the exhaust gain lives.
Required hardware
Racingline R600 intake or R600 bundle, uprated front mount intercooler (Airtec or Racingline), 3 inch sports cat or decat downpipe, then the custom Stage 2 file.
What's included
Fully custom file mapped around your exact hardware combination.
Every dyno booking gets before and after power runs and a printout.
Things to know
99 RON fuel is required.
Body style matters on the exhaust. Cobra Sport do different configurations for the 3 door, Sportback and Saloon, so check you're ordering the right one. Drop us a message if you're not sure.
A decat will fail an MOT and is sold for off road use only. If the car stays on the road go sports cat, the power difference is marginal.
Manual gearbox owners: a clutch upgrade is not optional at Stage 2. The standard clutch won't hold this torque.
Fitment
Audi S3 8V, 2.0 TFSI EA888 Gen 3, pre-facelift and facelift, GPF and non GPF. Manual, DQ250 and DQ381 S tronic.
Two ways to get it done
Book in at our Coventry workshop for a full custom dyno tune on our 4WD rolling road, or take the Flash At Home option and we'll send you a WP-Flasher device to load the file yourself wherever you are.
If you have datalogging equipment, we can check the file and make adjustments from your logs.
