Looking to up your boost limit on just about any BMW vehicle that runs a 3 or 4-wire BMW map sensor including but not limited to S58, B58, N54, N55, S55, S63, B48, B47, B42, B57, B46? We were too, so we decided to make a very easy plug-and-play kit for 3, and 4-wire BMW map sensors. These kits will allow you to completely replace the 3-wire sensor with one of our sensors, leave your stock 4-wire in place for IAT sensing, and move the power, ground, and sensor signal from the factory sensor to our sensor. These sensors have the proper scaling which will allow your tuner to simply change your map sensor scaling in the tune, and the factory ECU will be able to utilize the sensor voltage with no problem. We are offering these in 5 bar (58 psi), and 6 bar (72 psi), and each comes with a plug-and-play harness, and optional fittings for ease of installation.
Note: For the S58/B58 our Factory style Pre-Throttle map sensor is also 5 bar, and will work fine coupled with the post throttle kit, but the scaling is different, if you want matching Voltages Pre/Post throttle you can run two of these.
A variety of install pics can be found below and - Here
Scaling PDF Links: 5-Bar / 6-Bar
Features include:- Plug and Play harnesses with no wire splicing
- Output wire for connecting a PI or external controller to your post-throttle map sensor for the most stable signal that is not affected by throttle closure
- Different fittings are available for your plumbing needs.
- Can have matching voltage signals for pre/post throttle for ease of tuning, and boost reference
- B58/S58 etc Pre Throttle - 3 Wire Harness (Charge pipe to 1/8" NPT adapter needed, for B58/S58 90 degree adapter needed to provide sensor clearance)
- B58/S58 Post Throttle - 4 Wire Harness (Boost reference will be needed from manifold to sensor)
- F90 M5 Pre/Post Throttle - 4 Wire Harness (May need to repin) (Boost reference will be needed from manifold to sensor)
- Most all other platforms Pre/Post Throttle - 4 Wire Harness (May need to repin) (Boost reference will be needed from manifold to sensor)

VTT S55/N55 EWG Cast Aluminum Valve Cover
VTT is proud to introduce our S55/N55 EWG Cast Aluminum Valve Cover, designed for performance-driven BMW owners looking for a durable, stylish, and functional upgrade. This option provides a cost-effective alternative to our billet valve cover while still delivering enhanced engine bay aesthetics and eliminating the failure-prone factory plastic cover, which can crack over time.
Beyond durability, this valve cover removes the problematic factory PCV system, giving you complete control over how you set up your PCV. We highly recommend pairing it with a catch can for optimal performance. Additionally, this cover is perfect for single turbo conversions, offering increased clearance and improved heat resistance.

VTT is proud to offer our EWG "Direct Control System" or DCS! This is a completely new innovation for people looking to control the highest-flowing wastegate on the market using an existing BMW electronic actuator. This system will allow BMW owners who have a vehicle with Electronic Wastegates from the factory to utilize this system to control an externally wastegated turbo system, AND it will ALSO allow ANY vehicle to use this setup to control your own custom turbo system. This is done by utilizing our custom 7075 Billet aluminum bracket coupled with a Turbosmart Straight gate, and if needed an EWG controller made for us by DCCD Pro. This allows direct external wastegate control over any turbocharger system with or without EWG for the factory. Features:
- Utilizes the most current wastegate technology the Turbosmart Straight Gate. This gate allows maximum flow with minimal restriction, low drive pressure, and much more. Full details can be found here - https://www.turbosmart.com/product/electronic-straightgate-esg50-external-wastegate/
- Can be configured in multiple ways, and angles based on how you mount the adapter
- The adapter is 7075 Aluminum which has the strength of steel and weight of aluminum
- All connection fittings, are made from Nitronic 60 which has extremely high temperature and wear properties
- Zero Drive Pressure, no springs, no poppet valves, direct control over the gate using factory ECU logic
- Adaptable to ANY turbo system on any car to provide the ultimate in boost control!
