At JF Automotive we felt M-Power’s tuning effort was a bit weak for the costs involved. The MPPSK kit is a great idea, but 360BHP & 500Nm just isn’t enough for a performance enthusiast…and while they’re limited by marketing tactics, we’re not. This means we can offer a kit offering a better sound, and M4 performance for the same costings. Better than that, it’s available as a mail order kit that any local garage should be able to install in around 2-3hrs.
The kit is made up of two parts;
We’ve tried a number of exhausts, and the Remus is simply the best fitting, best quality system we’ve come across. There’s various options on the exhaust tips too, pictured at the bottom of the page. It’s a proven system that fits, flows well and sounds great. This makes it the ideal choice when building a tuning package for the car. Here’s a video;
We’ve got one of our famous adaptive tuning modules out, and created a loom & map for it to work correctly with the BMW engine. The adaptive tuning module isn’t your usual ‘dumb’ resistor in a box – it’s a fully equipped custom mappable, multi channel piggyback ECU and this allows us to accurately tune the car. All of this is a bit of a mouthful, so we tend to stick to ‘Tuning module’.
The tune is developed to run on premium unleaded, and we recommend Shell V-Power or Tesco Momentum 99 for best power figures. The car will still run on 95 octane fuel, but poor quality fuel will result in reduced performance. If the car is already filled with 95 octane fuel at time of purchasing the kit, please advise us and we’ll add an octane boosting additive to the fuel.
Should you have to take the car in for any warranty work the kit is very easily removable making it much harder for anyone to detect it was ever there. No permanent modifications are required under the bonnet, it’s a very simple plug and play affair. Pictures of the module are at the bottom of the page, and also an engine bay shot with the module installed – Maintains the OE factory appearance even when installed should anyone open the bonnet.
The results? 429BHP & 579NM. For perspective, the stock car makes 325BHP and 450Nm….the M-Performance kit makes 360BHP & 500Nm. A BMW M4 makes 425BHP & 550Nm.
This is around a 30% improvement in both power, and torque.
Pricing varies depending on exhaust tip options (pictured at bottom of page)
