Super easy install, took about 15 mins and the difference is night and day, how the car should have left the factory new
The extra power is there. First is noticeable at around 3000rpm and then after 5500 where the stock car starts to loose his breath. Too bad there is not enough grip to use all this power in first gears. I see 1.6 bar max boost from 0.9-1 bar stock. Regarding the custom track mode that replaces the slippery mode, actually it feels like only the accelerator response is changed, works like in sport mode, and the brake does not require so much effort, but still is not like in sport mode. Steering and suspension are soft like in normal mode, ESC is on, start-stop on, no pops and bangs. This is a nice addition since sometimes soft suspension is more adequate, too bad the brake still doesn't feel like in the other modes. It's not as bad as in the original slippery mode, but it feels different than the other modes.
Had the m330 installed last Friday, certainly brings the car alive! Highly recommend
