M3 F80 - best tuner in Europe

[sasa.baska]

Hi,
I am looking at stage 1 upgrade for my M3 F80?

So far my favorite tuners are AC Schnitzer and Novatune stage 1 or 2.

Both offer around 510 - 520 ps and 640 - 650 nm....other tunners offer even more power and especially more torque, but my priority is durability of the engine/clutch as my M3 is daily car and thinking to keep it for many years.

Do you reccomend some other more realiable tuner in Europe?

Thanks for sharing your thoughts
