Finally the car now feels sorted, kind of reminds me of going from the MP350 to the MR375 on my mk2. Much better oomph all throughout the rev range and car just wants to go all the time, finally the mk3 puts a smile on my face every-time I take it out.
I always loved my M380 car that was upgraded by Mountune HQ, but the M400 is on another level. Firstly the boost comes in much earlier and much stronger. It makes the car feel incredibly powerful but also the power and torque band is a lot more accessible. This makes the car easy to drive in a lazy manner using the torque. However when you're in the mood, use all of the revs and be prepared to hold on because the M400 is savagely fast. It feels way more powerful than the numbers on paper suggest and I can only put this down to the way the power is delivered and the new map is setup. It's utterly addictive!
Had some of kit fitted previously with the M380 package. Top quality service and workmanship by Mountune HQ
