Absolutely amazing, I brought all the hardware for the MR230 and fitted everything while already being MP215. Looking at Mountune's chart on power differences i was a little worried as I wasn't sure if i would notice a big difference between MP215 and MR230. Being at the stage where I needed to get it done as I fitted the sports cat and the engine light was on, i didn't really have a choice. Luckily Mountune is fairly local to me and i waited with the vehicle while it was being fitted and i was talking to Fred saying i'm not sure what to expect. Fred said "MR230 is one of my favourite upgrades we have ever offered, it makes a great car even better" that really made we quite excited to drive the car. On the way home I have to agree its an animal the way it puts the power down is amazing. Highly recommend this if you have a MK7.5 ST 180. As always it was a real pleasure seeing the team again, although being in this Period of Uncertainty, but they are handling the issue very well.
Wow! What a difference this makes to the car. A big step up from MP215. I love this tune, I would recommend stickier tires and wider wheels to cope with the extra grunt through.
Nice upgrade from MP215, the torque is much bigger now and the car feels very much quicker. The torque limit is gone, and I can use 2nd gear a lot more. Pulls great in every gear. Big smiles
