nice car selçuk congrats..
i also drive a 2015 lci 320i remapped to stg1plus and a itg profilter. My 100-200 is about 16.9 and 0-100 about 6.4. Im considering catless downpipes following week.What is your peak boost calculations? Mine has 1.49bar peak and it ends with 1.10bar. Also i like to know where did you get the gfb dv+ in ankara ? And do you think it makes a difference? And the last question, how much is it?
