BMW Performance Parts: Dinan Stage 2 Performance Engine Software for BMW 'F' Chassis N55 Engine (D900-N55-S2)

Product Features:

Stage 1 have you wanting more? Stage 2 Dinan performance engine tuning for  ‘F’ chassis N55 platforms provides a new found level of exhilaration and enjoyment for you to enjoy. Taking advantage of supporting hardware (Dinan big turbo and an upgraded intercooler), the stage 2 engine calibration takes a significant step up in performance. Yielding nearly 40 WHP / 60 lb-ft of torque more on pump gas over stage 1 (over 70 WHP / 80 lb-ft of torque on race gas). That's +120 WHP / +160lb-ft of torque over stock on pump gas (nearly +170 WHP / +210 lb-ft of torque on race gas)! That type of bump in power equates to a transformation akin to purchasing a completely different vehicle. 

  • More Power. Max gains of 169 WHP / 206 lb-ft of torque over stock on 104 octane and in conjunction with the Dinan big turbo and an upgraded intercooler. Consult the product page for performance charts for additional octanes.
  • Dinan Stage 2 performance software includes a limited lifetime warranty against defects in the software and provides free updates and reflashes as they become available. Labor or shipping charges are not included in the warranty.
  • Access to numerous octane calibrations (91, 93, 100 and 104) depending on your needs.
  • Full map rescaling for drivability from idle to wide-open throttle and everywhere in between.
  • Optimized boost control, cam phasing, fueling, airflow and temperature controls for maximum power output that is also safe and reliable.
  • Top speed governor (VMAX) removed.
  • Sport Cooling mode in sport / manual modes.
  • Upgradeable from DINANTRONICS Elite via trade-in program.
  • Retains all BMW factory engine safeguards.
  • Torque gains drastically improve acceleration.
  • Sport gauges rescaled to reflect higher than stock power output.
  • Downloads through the OBD2 Port - See compatibility notice below.
While increases in power to this scale typically come at a cost to the engine’s durability, this is typically due to improper calibrations that are simply after one goal regardless of engine health – maximum power. Dinan’s stage 2 mappings when used in conjunction with supporting hardware are safe and reliable without sacrificing long-term reliability or performance. Dinan performance engine software is so much more than just turning up the turbo boost after all. It is a fully re-tuned engine management program that maximizes power while keeping all the BMW factory safeguards in place. In most cases Dinan software engineers also implement their own additional safety precautions in order to guarantee flawless performance that may not have been needed with factory power levels/programming. Protecting your BMW, while giving the most performance, is the definition of "Performance Without Sacrifice". To do just that, drivetrain and engine components are analyzed for strength, and then the calibration is tested on the dyno and in the real world for durability and drivability. This process has been a cornerstone of Dinan software development for decades and a major reason why Dinan performance tunes are often labelled as being the smoothest, factory-like solution in the marketplace.
With factory-like reliability/safety and staggering performance, it’s hard to find a reason not to upgrade to stage 2. That “new car” you always wanted is hidden right in front of you. Let Dinan give you the keys so you can enjoy it.

COMPATABILITY NOTICE:  The N55 engine and its multitude of variants account for several 100 unique box codes across various platforms. While Dinan has created files for a great number of these permutations, there is a chance you may have a box code that we have not seen.
