Hi everyone, in a few weeks ill be fitting my go faster parts and im just wondering who is offering the best map for the most gains (im guessing this might spark a debate)

I have a 2000 c70 t5 and will be fitting green injectors, bsr intake with heatshield, ported s60r manifold and a 19t with a 20t compressor wheel.

Im obviously planning on running low boost until the map is sorted. I want one that can take into context what engine mods i have done and get the most out of them, possibly a custom map would be best?

Thanks in advance
