I owned a facelift mustang gt and just purchased a mk4 st so wanted that extra punch so it didn't feel like such a downgrade in performance..... I had the ST stock for one day before i installed the m330 kit and mountune panel filter. All I have to say is wow! I swear this feels faster than the mustang! The torque is absolutely insane for the size of car it is. Any gear, any rev range and it's instant. Proper throws you back into your seat. Can't recommend this enough. The car is an absolute weapon on b roads. The installation process was very easy and the kit came with a handy little step by step book so you can't go wrong. Overall, very impressed and look forward to upgrading to the m365 package. The only thing which was not what i was expected is the pops and bangs. They seem to be just as random and sometimes non existent as with a stock st. But when they do happen it's brilliant. Sounds like a proper rally car. This isn't a bad point BTW, i was just expecting more.
Well done Mountune! Nice upgrade! Thx
Bought at the Ford Fair with a bargain £99 off the price. Makes the Focus even better than it was.
