Sveiki! Welcome fellow Lithuanian. The F30 320d is a great platform for tuning. Stage 1 remap will transform the car - expect around 230-240hp from the B47. If you need recommendations for tuners in Lithuania, feel free to ask. Theres a few good ones in Vilnius and Kaunas.
Welcome! Another Lithuanian here. The 320d is probably the most popular BMW in the Baltics for a reason - great fuel economy and responds amazingly to tuning. Start with a stage 1 remap and youll be hooked.
