This stage of tune is specifically designed to optimize the top end power that comes inherently with an upgraded turbo. While in stock, and lightly tuned, configurations the engine tends to fall off rather dramatically after 5000-5500 RPM with the big turbo installed the the cars continue to make additional power all the way to red-line. This results in some very impressive maximum gains of up to 152 HP and 123 lb-ft of torque in certain instances. There are a variety of different performance data set numbers listed below depending on application and other factors.     DINANTRONICS Performance Tuner for the F22 / F23 M235i, F30 / F34 335i (w/ MPPK, Auto Trans.) & F32 / F36 435i (w/ MPPK, Auto Trans.)ONLY applicable to cars equipped with an electronic wastegate.Pre-order Only.

It is also the only tuning device emissions legal in all fifty states. The ultimate objective of developing this piece of technology was to provide the ability to control every signal entering and exiting the BMW factory Engine Control Unit. These items are unique to Dinan and together they embody the apex of performance engineering in a powerful, reliable, and warrantied package. Upgraded Fuel PumpFor the F3x N20 & N55 Engines(Full Assembly or Upgrade Kit)     Part Numbers: R420-0002N20/N55 F-Series Upgraded Fuel Pump (Full Assembly) Retail Price: $899.00R420-0001N20/N55 F-Series Upgraded Fuel Pump Kit(Upgrade Kit) Retail Price: $229.00   With increased power comes increased demand on the fueling system to satiate that demand. The stock fuel pump is incapable of delivering consistent fuel flow at low fuel tank levels for high output applications under heavy load resulting in the possibility of inconsistent power delivery.Dinan‘s upgraded fuel pump enhances the pump’s ability to draw fuel, and allows full flow of fuel to the engine during high demand operation. This means that at no time will you suddenly experience a loss of power due to inadequate fuel supply and you can push the car hard continuously during a track event or other high demand application without fear. Perhaps best of all is the Dinan modified fuel pump can be properly controlled by the stock DME resulting in no faults or warnings on the iDrive. Just consistent power all the way to redline.    For those that want a fully assembled and modified fuel pump please use R420-0002. For those who wish to modify their existing fuel pump using a Dinan supplied component kit use R420-0001.    Benefits of the Dinan N20/N55 F-Series Upgraded Fuel Pump:

  • Allows consistent fuel flow to the engine during high demand operation. 
  • Stock DME can properly control the Dinan modified pump so no faults or warning are presented. 
  • Dinan components consist of CNC stainless steel adapters, stainless clamps, and high quality automobile grade submersible fuel hose. 
  • Includes new modified fuel pump and O-Rings which must be replaced during pump installation.
  • No other modifications needed.  
  • NO DINAN WARRANTY

Free Flow Stainless ExhaustFor the F85 X5M F86 X6M      Part Numbers: D660-0054Free Flow Stainless Exhaust w/ Polished Tips For the BMW F85 X5M & F86 X6M Retail Price: $2059.00D660-0054-BLKFree Flow Stainless Exhaust w/ BlackTips For the BMW F85 X5M & F86 X6M Retail Price: $2059.00   The F85 X5M and F86 X6M are the quintessential SUV in terms of power and performance with accolades in numerous periodicals crowning them the pinnacle of their class. With the possibility of putting down over 700 HP with a base tune these vehicles are no slouch. Dinanengineers wanted to match this impressive feat with an equally impressive exhaust tone that let those around these SUV’s hear the power that lies beneath the hood as well as be able to show it. Take a listen to the video clip below and judge for yourself if we were successful.    The exhaust system was designed to improve exhaust flow by reducing back pressure, resulting in increased power output and a deep sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration.  Dinan also incorporates a Helmholtz chamber design that reduces resonance or “drone” at low RPM. The technology within the can is matched in impressiveness by its outward appearance and design as the system is built to exacting specifications to ensure a simplistic bolt-on installation. It is made from 100% 16 gauge 304 stainless steel and will resist corrosion for years to come. The design features quad 89mm (3.5″) black ceramic exhaust tips for a tasteful, high-performance look.   Benefits of the Dinan Free Flow Exhaust for the F85 X5M and F86 X6M:

  • 8 HP @ 6000 RPM, 7 FT-LB @ 6000 RPM
  • Quad 89mm (3.5″) laser engraved black ceramic exhaust tips
  • Enjoyably louder, sportier sound with a deep growl
  • Helmholtz chamber to reduce drone
  • Computer controlled valve limits noise during low speed driving; valve opens fully during high-load conditions to allow free flow
  • 100% 304 stainless steel construction
  • Bolt-on Installation

Performance Spring Set + Supplemental Ride Quality & Handling Kit For the F30 340i (RWD Only)    Part Numbers: D100-0931Performance Spring SetFor the BMW F30 340i (RWD) Retail Price: $299.00D193-3201Ride Quality and Handling KitFor the BMW F30 340i (RWD) Retail Price: $184.00 Only available for the RWD F30 340i. xDrive compatibility is forthcoming.     Suspension systems that not only transform the stance of the vehicle but also maintain ride quality and improve upon handling are what Dinan suspensions are known for. This is accomplished by pairing springs sets with bump stops, spring perches or both to maintain suspension travel resulting in a smooth ride while also improving mechanical grip and handling. This is what makes Dinan suspension systems unique. While we are able to sell each component separately it is highly recommend that both the spring sets and the supplemental ride quality and handling kits are used in tandem in order to maintain the Dinan quality standards our customers are used to. Experience the Dinan difference with this combination and enjoy the ride it provides.      Dinan‘s Performance Spring set for the F30 340i (non xDrive) provides greater control over body roll by virtue of carefully calibrated spring rates. Additionally, Dinan lowers the 340i by a full 1″ in front and 1″ in the rear for improved suspension geometry and an even more aggressive stance. The Dinan springs are CNC wound with high tensile chrome silicon wire and shot peened for stress relief to last the life of the car. The 25% increase in stiffness in front and 34% increase in the rear will reduce the rear suspension compression under acceleration and front suspension compression (or dive) under braking, giving your car a more controlled feel. TheDinan performance springs will also provide a noticeable improvement in grip, for high speed driving situations that will inspire confidence in your car’s capabilities. The reduced body roll makes the steering more responsive to driver input and will be noticed at speeds as low as 20 mph, up to the top speed of the vehicle.    Benefits of the Dinan Performance Spring Set for the F30 340i (non xDrive):

  • 25% increase in spring stiffness in front, 34% increase in the rear. 
  • Lowers the vehicle 1″ in front and 1″ in the rear
  • Preset to prevent spring sag
  • Compatible with both conventional and factory electronic shocks

NOTE – Dinan Performance Spring sets should be purchased and installed with the corresponding Ride Quality and Handling Kit to achieve the advertised ride height, performance, and ride quality. While not explicitly required, if the matching component is not purchased and installed you will get less than favorable results in the form of poor ride quality and improper handling traits. While we will maintain a full warranty on product defects, any claims against the car’s improper handling/ride quality traits due to not purchasing the corresponding handling kit will not be warranted.
