Hi, first of all, I just want to say hi to everyone, I am a new comer. Anyway, I don't see a specific engine tuning section on this forum, but this is 850 related, so I will post here. Well, does any of you know if there is an ECU upgrade avaliable for NA 850 engine? I had searched the internet, nothing comes up except for Eastern Aerospace. Anyone heard of this company? How is it? Thanks.
