BMW E92 335i Stage 2 with Downpipe & Burbles
This BMW E92 335i N55 went from 306hp and 400Nm to 390hp and 550Nm with our Stage 2 calibration, a gain of 84hp and 150Nm.
Built for Stage 2
The car had supporting hardware fitted first, including a Milltek downpipe, a BMS charge pipe and an intake pipe. With the engine breathing more freely, the Stage 2 map was written around those parts and carried out on the same visit as the install.
Add-ons
- Speed limiter solution
- Cold start solution
- Burble activation
What makes the E92 335i good to tune?
Its N55 3.0 twin-scroll turbo straight-six responds superbly to software and supporting parts. We tune E-series BMWs like this at your home or workplace across Bristol, North Somerset, Somerset and South Wales.
About this job
The results
This BMW E92 335i now makes 390hp, up from 306hp as standard: 84hp more, an increase of around 27%.
Torque rose from 400Nm to 550Nm (+150Nm), which is what you feel most in everyday driving: stronger pull from low revs and easier overtaking.
What the work involved
This was a Stage 2 calibration, written for a car with supporting hardware such as intake, intercooler or exhaust upgrades. With the engine breathing more freely, the software can safely ask more of it than a Stage 1 map.
How we carried it out
- Diagnostic scan for stored faults before any work
- Stabilised power supply connected while programming
- Original software read and saved, so the car can be returned to standard
- Calibration written, then the car checked again afterwards
