Audi B8 S5/S4 3.0 TFSI  ECU Performance Software and Power Pulley

New Release From VF-Engineering

Audi B8 S5/S4 3.0 TFSI
ECU Performance Software and Power Pulley

VF-Engineering and HEX TUNING have achieved outstanding results with the supercharged 3-liter V6 TFSI engine found within the current generation of S5 and S4 vehicles with Simos 8 EMS. 

This adaptive and intelligent ECU manages engine health and output during constantly changing environmental and load conditions. It allowed HEX TUNING a sizable and yet safe latitude engineers while focusing on several parameters within the engine’s performance envelope including:

• Enhanced partial throttle/full throttle response
• Optimized air/fuel ratios
• Enhanced torque management
• Enhanced transmission/shift response
• Recalibrated variable valve timing
• Optimized boost management and wastegate control
• Limiters and governors raised/and or removed
• Designed and Made in California, USA.

The revised software is loaded with HEX TUNING’s proprietary module through the Audi’s OBDII port. The module then plugs into a standard laptop computer and the HEX interface does the rest.

HEX software is augmented with VF-Engineering’s supercharger Power Pulley, a beautiful piece that’s been carved from aircraft-spec aluminum and balanced for optimal, high-speed rotation. The VFE Power Pulley provides significantly increased supercharger air flow and helps create substantial gains to both HP and torque. VFE’s Mustang MD500-AWD chassis dyno recorded an additional 83 ft-lb torque and 108 HP using less-than-deal 91 octane fuel.
In less than two hours the S5 is transformed from a GT car to a genuine, fire-breathing GTS.
