Hello, in your opinion, what is the optimal EOI for the M57 engines and at what rpm? Should I stick to the stock EOI of the car as much as possible when tuning or not? I calculated the Eoi values ​​for my M57231HP engine at 2250 rpm and I have 5.77 and at 4000 rpm I have 1.20 Eoi. Can I calculate how much to increase the SOI or the pressure in the rail when tuning, but my question is what exactly Eoi should I get and what are the limits.
