Stage 1 Performance Tune for BMW N55B30 Engine

The DUDMD Tuning Stage 1 Performance Tune is designed for the BMW N55B30 engine, specifically for F30 and F31 335i/335xi models produced between 2013 and 2015. This ECU tuning software aims to enhance vehicle performance by modifying key engine parameters. The tuning process targets torque limiter maps, boost levels, fuel maps, and ignition timing advance. These adjustments are made to safely increase horsepower and torque output, while prioritizing good drivability and retaining factory fail-safes and limp protection. The estimated gains for this Stage 1 tune are up to 79 WHP and 83 WTQ at specific RPM ranges. Installation can be performed via two methods: Bench Flash, where the ECU is mailed in for programming, or Remote Flash. The Remote Flash option includes an ENET cable for connection to the vehicle's OBD2 port and a laptop's Ethernet port. Users will receive OBD2 flasher software and a tuning file via email, with remote assistance available if needed. A Windows 8 or newer laptop is required for the remote flash process. DUDMD Tuning explicitly states they do not offer tuning for emission deletes, nor do they disable catalytic converters or secondary air pump systems. Furthermore, tuning services are not provided to residents of California. The product is listed as in stock with a sale price of $435.00, excluding tax, with shipping calculated at checkout.
