Are speed boost and engine power mult redundant?

[rkwapisz]

Perhaps I don't understand the mechanics of SET_VEHICLE_FORWARD_SPEED, but I'm curious if there is value in maintaining both the "speed boost" and "engine multiplier" feature.

I find that the engine multiplier itself works very well if I'm just looking to turbo down a highway, but haven't been able to compare it much to the speed booster.

Do these two features more-or-less do the same thing (make you go faster)? If so, do we need both?

This should have been made against one of the forks. Whoops.
