  • 2020 G30 M550i xDrive
  • 2020 G11 750i xDrive
  • 2019-2020 G14/G15/G18 M850i xDrive

The Quick and Dirty (Features and Benefits):

  • More Power: Stage 1: Max gains of 207 WHP / 205 lb-ft of torque over stock on E85 or 108 WHP / 141 lb-ft of torque over stock with 93 octane. Consult the performance charts for additional octanes and their associated data. Dinan +: Max gains of 81 WHP / 123 lb-ft of torque over stock with 91 octane. Consult the performance charts for additional data.
  • Warranty: Dinan Stage 1 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. Dinan + performance software matches the factory new car warranty (4year / 50,000 mi) and is the warranty protection commonly associated with the Dinan brand.
  • Stage 1 affords access to numerous octane calibrations depending on your needs (91, 93, 100, 104 and E85). Switching between mappings would require a reflash at a Dinan authorized dealer. Dinan + is limited to a single map (91).
  • Full map rescaling for drivability from idle to wide-open throttle and everywhere in between.
  • Optimized boost control, cam phasing, lambda targeting, fueling, airflow and temperature controls for maximum power output that is also safe and reliable.
  • Retains all BMW factory engine safeguards and adds numerous additional safety protections.
  • Top speed governor (VMAX) removed.
  • Torque by gear strategies implemented for maximum power output and traction.
  • Sport mode cooling that targets lower coolant temperatures added for optimum track effectiveness.
  • Pedal feel improved to naturally align with the increased torque output.
  • Sport gauges rescaled to reflect higher than stock power output.
  • Torque reserve feature enabled for increased boost pressure during launch control.

The Story:

Even though a step below the S63TU4 and the immense power that that M engine wields, the N63TU3 still shares much of the same V8 architecture and is plenty capable of feats most powerplants can only imagine. Paired with a Dinan Stage 1 calibration yielding max gains on pump gas of nearly +110 WHP and +140 lb-ft of torque, the N63TU3 and the M550i/M850i it powers, instantly evens the playing field and puts the platforms on level footing with the alphas of the brand. The imposing gains are eye-opening on their own but considering that those figures are with no additional modifications or alterations to the catalysts, it's an even more impressive achievement. Utilize E85 and the gains jump yet another factor of fun -- a mind boggling additional +207 WHP and +205 lb-ft of torque to be exact. Even if you wish to retain the 4yr/50k warranty, maximum gains are far from paltry with the Dinan+ variant registering gains of 81 WHP and 123 lb-ft of torque. No matter if you opt for the peace of mind or pursue the greatest power potential you will enjoy the results and the childlike grin it puts on your face.

While increases in power at 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 calibrations 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.

NOTE: Compatibility is limited to vehicles with the N63TU3 engine from the 2020 MY (specifically up to a 06/2020 build date). 2019 and prior M550i's/750i's with the N63TU2 engine & 2021+ MY's with updated encryption are not supported at this time.
