Dear OP,

are you tuning with logs or without?

for 2450mbar u do not need such high durations, maybe 31 degrees is enough....

I just checked, 2450mBar is for 150hp, 54,5mg/str required @ 3990 RPM

You can check the original file of Ibiza BPX PD160. Is almost perfect for what you need. It has the same injectors as you so you can copy duration maps from there.
