Whooosh!! The 275 kit is decent, adding a worthwhile extra 25PS/40Nm over standard, but you could just save time, add the additional hardware and jump straight in for for the MR300 calibration, taking it up to 300PS/470Nm, you won't be disappointed. Some may think 50PS/110Nm gain over stock trim is marginal, but when you feel it kick in, you'll come to the quick realisation that it's actually a bit special. MR300 totally transforms the drive, add a Quaife ATB diff into the mix and it becomes the car you always wanted.
Having had all the parts fitted for MR300 I decided it was time to upgrade the map. Unfortunately I did this at the start of lockdown. So I was unable to drive the car. Now I'm back to work and using the car daily i feel it's a good time to review the map. It's great. Nice smooth power delivery. Not sure what I was expecting. My car was a strong 275 before and I cant really notice an additional 25bhp. What I can notice is the extra torque. And it makes the car much easier to live with. I think before on the MP275 map it was great but something was missing. The MR300 fills that gap. It's a no brainer if you have the hardware needed. The only down side is it never came with a new badge and you have to pay postage for an email.
You should've received an m-flag badge with this kit, so if you didn't, please contact our sales team. Glad you're enjoying the MR300 otherwise!
Bit confusing trying to update firmware to controller. Key wouldn’t be seen by laptop when trying to download but when I had a chat with the tech gurus at Mountune the confirmed it had auto loaded to controller. Connected to car and 5 mins later software download complete. Focus ST now total awesome with 300bhp on tap. Excellent purchase just visual upgrades now.
