BMW 535d Stage 1 Tuning (2014-2018)

What It Is
A Stage 1 performance tune for the BMW 535d, adding +90 lb-ft of torque and +60 hp. Tuning is done entirely with stock components, no supporting hardware upgrades needed.

How the Tune Is Delivered

• 2014-2015: Via the Q-PRO+ device from your driveway. You'll email a copy of your stock file to KermaTDI's tuning department and receive a tuned file back. If you can attach a document to an email, you can handle this step yourself.
• 2016-2018: Via a remote tuning session using a Kerma-supplied Enet cable. Requires a Windows-based laptop and a good internet connection at the tuning location.

Performance Gains

• +90 lb-ft of torque, the number that drives how the 535d actually feels to accelerate
• +60 hp alongside the torque gain
• More pull through the mid and top RPM range, useful for passing and spirited driving
• Turbo lag noticeably reduced, with sharper throttle response
• Up to 10% MPG improvement on long-distance driving

Switching Between Stock and Tuned
The Q-PRO+ lets you switch between stock and tuned settings, useful for dealer visits or diagnostic work.

Want More? Stage 2 Is Available
A Stage 2 engine and transmission tune is also available as a separate upgrade, which additionally recalibrates the transmission to match the added power. Remote tuning with an Enet cable is required for Stage 2.

Emissions Requirement
All emissions systems must remain intact and installed. Exhaust flow is not a limiting factor for this tune's output.
