BMW 530i tuning
The BMW 530i (G30 / G31, 2017–2023) runs the B48 2.0L turbocharged inline-four and leaves the factory at 248 bhp · 350 Nm, Rear-wheel drive, 8-speed ZF automatic. Samuel tunes the G30 Saloon and G31 Touring to the same standard — every map hand-calibrated for the specific car, its fuel grade and its installed hardware, not a base file loaded and left. 530i Stage 1 alone takes it from 248 bhp · 350 Nm to 310 bhp · 520 Nm on the standard turbo, flashed over OBD on BM3, MHD or MG Flasher.
Add the Stage 2 hardware and the 530i targets 340 bhp · 550 Nm; from there the B48 stretches to around 500 bhp on a hybrid or big-turbo build with supporting fuelling. Whichever stage suits the 530i, the file is delivered within 24 hours and is fully reversible to the supplied stock calibration.

BMW 530i tuning, stages, hardware and what to expect from the G30 B48
The G30 530i runs the B48, BMW's 2.0-litre single-turbocharged inline-four, in saloon and G31 Touring form. From the factory, BMW calibrated the 530i to 248 bhp / 350 Nm, a more conservative limiter than the 330i / 430i despite shared engine hardware. BMW 530i tuning with Samuel closes that gap and unlocks the same Stage 1 / Stage 2 ceiling the rest of the B48 family targets. The G30 saloon and G31 Touring use the same map; only the build sheet differs slightly for the wagon exhaust geometry.
Stage 1
310 bhp · 520 Nm
No hardware required. The MG1CS003 DME is flashed via the OBD port, boost pressure, ignition timing, fuel delivery and torque limiters all revised. BMW 530i Stage 1 unlocks 310 bhp / 520 Nm from the OEM hardware (up from 248 / 350 stock), with a substantially broader torque curve through the 5 Series mid-range.
Every 530i tune Samuel produces is calibrated individually for the specific car, fuel grade and installed hardware, not a base map loaded and left. BMW 530i tuning done correctly accounts for the G30 chassis weight, the 8HP gearbox calibration and UK fuel quality; the map is reviewed against your data logs after the first flash and revised before sign-off.

FAQ
530i tuning — frequently asked questions
530i Stage 1 lifts the B48 from a stock 248 bhp · 350 Nm to 310 bhp · 520 Nm, with no hardware required. The map is flashed through the OBD port on BM3, MHD or MG Flasher and is the starting point for almost every 530i owner — broader torque and sharper throttle response from the factory hardware.
This page covers the G30 Saloon and G31 Touring (G30 / G31). They share the B48 2.0L turbocharged inline-four and run the same core calibration, but every 530i tune Samuel delivers is tailored to your exact car, fuel grade and installed hardware — never a base map loaded and left.
Stage 2 on the 530i targets 340 bhp · 550 Nm and needs downpipe + intake. Everything else — turbo, fuel system, intercooler — holds within the Stage 2 figures on the B48.
On the right hardware spec the B48 in the 530i reaches around 500 bhp. Stage 1 and Stage 2 run the standard turbo; beyond that needs a hybrid or full big-turbo conversion with supporting fuelling, and the calibration is built bespoke per car.
Remotely. Once Samuel has your build details, the calibrated 530i map is delivered to your flashing tool account (BM3, MHD or MG Flasher) within 24 hours and you flash it yourself over OBD in about 15 minutes. It's fully reversible — the original B48 stock file is supplied before you flash, so the car can return to factory at any time.
A factory warranty can be voided if BMW shows a tune caused a specific failure, so it's a personal call. Samuel's 530i maps are calibrated to stay within the mechanical limits of the B48 hardware, and because the tune is reversible to stock before any dealer visit, many owners run a tuned 530i without issue.
