SOI Advice

[Running rough]

Would the cold Canadian winter effect final crank angle, what works in the desert probly will not be optimized for colder climates, apparently stock cals use mass flow calculations to get the boost the tune is looking for, I am led to believe @m*m^2 style tuning uses a fixed position at a given rpm and load meaning you more then likely will have more boost the colder and denser the air is that is why the turbo mapping has to be fine tuned to the type of truck and environment it will run in, it is said that the stock mass flow calculation turbo mapping can not touch the @m*m^2 custom mapping in both performance and fuel efficiency when it is dialled in correctly for the given truck and application, soi is another thing but I would think the cold air up here combined with extremely advanced timing i would have a bad feeling about it under heavy load, for instance I can notice slight crank flex vibrations, in cold weather with the high torque cals, and I believe the timing is mostly stock, take it in to warmer summer conditions and the crank flex disappears, now if a guy advance the timing to much I am sure the vibrations would increase, and that can't be good, but as always don't lug the snot out of your engines if you want maximum life,
