Hi I have this on mine, and I liked it with the air filter, it only gives 8bhp not tested, does feel a little aggressive,
But I wouldn't say it was life changing. The choice of maps and diagnostic is handy, with more mods its meant to add more, paid about 150 for mine so quite happy with it ,
Add an exhaust cam pully and sports cat, or decat for better gains, shows some info on there web
