BMW 335i Stage 1 Remap

Name: BMW 335i Stage 1 Remap
Brand: BMW

On BMW 335i naturally aspirated engines a Stage 1 remap refines the ignition timing, fuelling and throttle response maps. Without a turbo the power gain is smaller than on turbocharged engines; the difference is felt mostly in throttle response and the mid-range. No hardware is changed and the original software is backed up.

How much bhp does BMW 335i chip tuning add?

It depends on the generation and the stock output. 335i engines with 306–326 bhp reach 360–370 bhp with a Stage 1 remap; the largest gain is +64 bhp (E90/E91 335i - N55 Twinscroll - 306hp). Pick your version in the table below.

Frequently asked questions

How much bhp does BMW 335i chip tuning add?

What is the difference between Stage 1 and Stage 2 on the BMW 335i?

Stage 1 is software only: no part of the car is changed and the figures in the table apply to this software. Stage 2 is software prepared for hardware changes such as the exhaust, intercooler or intake; the hardware comes first, then the software.

Will chip tuning damage the engine?

No. Values stay inside the safety margin the manufacturer leaves; engine, gearbox and turbo limits are not exceeded. Every file is verified with a road test and data logging. If the car needs maintenance first (worn injectors, blocked filter, weak clutch) we tell you before starting.

Will my fuel consumption go up?

With the same driving style it usually drops, because you hold the same speed at lower revs and less throttle. If you use the extra power, consumption naturally rises. It is down to your right foot.

How long does it take? Do I leave the car?

Most cars take 1–2 hours and you get the car back the same day; no need to leave it. Some models need the ECU removed, which takes longer — we tell you when booking.

Can I go back to stock later?

Yes. The original file is read and archived before any work. We restore the factory software free of charge whenever you ask.
