I have the programming ability to make it, its just a matter of figuring the the best way ( without pissing off the developers ) to do it.
im currently trying to figure out where/how the game stores the car's data in memory..so far, i know its not working from the the horsepower numbers, its gotta have some sort of multiplier value rather than using the horsepower value itself.
ie: 14 rather than 490.
to be honest though, im not sure the came has any sort of logic as far as boost pressure. i think thats just a boolean variable that turns on off certain sounds/graphics. but, im not sure yet...im new to the game and looking into how it works.
