B48 Custom Tune (Gen 1 & Gen 2)

B48 Custom Calibration. Small Engine, Done Right.
Built around your setup. Refined through real data. Delivered properly.

The B48 is often overpushed in the low end, big torque hit, then explodes.

We smooth that out and build power the right way.

Example setups:

• Hybrid turbo builds around 420whp
• Real-world 100–200km/h in the 8-second range

Not chasing numbers, just making the car fast where it counts.

No lean runs, no excessive timing just to print a number. The focus is real power — consistent, repeatable, and proven both on the dyno and on the road.

Up to 4 switchable maps available depending on your setup. Fully supported on MHD Tuning and bootmod3.
