Stage 4 performance package for the 2014+ F80 M3, F82 M4 and 2019+ F87 M2 Competition combines our awesome Epic Motorsports software tune and the functional Injen cold air intake system. Both pieces have been dyno-tested on our in-house Dynojet and have real-world performance gains.
The Injen intake is a complete replacement for the stock airboxes using roto-molded polyethylene plastic. Not only were we impressed with the quality and fitment of this intake but it actually made power: +22hp / +27ft-lbs of torque on the BimmerWorld dyno. Injen engineers design their intakes to carefully manage air velocity and air pressure using the Venturi Effect and velocity stacks. They also used the largest filter they could fit in the stock locations. With greater surface area and better flow there is more air available to make more power. The Injen Evolution intake fits with our belief that solid engineering and testing produces the best performance rather than flashy materials and marketing.
Our Epic Performance Software is so much more than just a reflash of CS or GTS software! We built our software tune with elements of both as well as the GT4 racecar we campaign in the IMSA and SRO GT4 series. Epic Motorsport knows there are higher limits that can be safely and reliably achieved thanks to their experience as one of the industry's only true engine tuners. Epic does not produce short-term gains to use in marketing material. We also do not ignore factory-implemented environmental limitations intended to protect your engine or unintentionally adjust maps or tables that we have a poor understanding of or that induce unknown variables. Epic software is a fully developed solution and we don't stop at "really good" or even "great" - our software is exceptional.
How exceptional? 84 peak hp and 107 peak ft-lbs more than stock! We more than double the torque gains of the GTS software between 3,000-5,700 RPM! The M3/M4 is capable of so much power and torque that it is a truly raunchy car to drive. At 3,000 RPM we make over 50 ft-lbs more torque than stock and by 4,250 RPM we're making 120 ft-lbs more! Without traction control on, be prepared to correct with both throttle and steering immediately because this car has earned the nickname, ‘White Knuckle Thrill Ride’!
We also retained several GTS and GT4 elements in our software:
Recalibrated Sports Display: the iDrive Sport Display has been rescaled to accurately reflect the new power and torque changes
Exhaust Burble: The car now has a very pleasant exhaust burble when you decelerate off-throttle, and under hard acceleration and then snapping off throttle, the exhaust cracks like a GT racecar. This is more pronounced with each Mode - relatively quiet in Efficient, bigger pop in Sport, and a firecracker snap in Sport Plus. There’s a little extra throttle blip on startup too.
GTS Steering: The stock steering is too light and over-boosted and we feel the GTS steering effort is just right.
GT4 Track Elements: We have retained several GT4 features that make our calibration even more suited for track and performance use, for extended periods of time, and without costly damage in the harsh track environment.
Peak power output does not change with the software & intake combination. The Injen's torque increase comes lower in the RPM range. The torque gain is there but will not show when advertising peak power gains.
New spark plugs are recommended (see link below). Fresh plugs are essential to making any power on turbo engines (tuned or stock).
* 2019 Software Update (Important!) (click to expand)A recent software update by BMW has disabled flashing the computer via the OBD port. If your car has been serviced by a BMW dealer since March, 2019 you likely have this locked version and your car cannot be tuned with any flashing tool. Please contact us for alternatives. Additional Consideration (click to expand)Increasing performance, whether by software tuning or hardware changes, will accelerate wear and tear throughout the car. Turbos, driveline components, brakes, and especially tires will experience shorter lifespans with the addition of more power and torque. This is not specific to any one product in particular and should be acknowledged and accepted by the purchaser, installer, and user of the product(s). BMW produces vehicles with a compromise among performance, comfort, consumer demand, and warranty obligations. Modifying your car beyond what the factory designed may realize shortcomings in one or more of those areas. BimmerWorld strongly encourages you to drive safely and responsibly and participate in advanced driver training courses. Notice of Emissions Non-Compliance.
