When switching from map 3 to say map 7, map 7 will always feel faster at first....

The reason is in your case your octane level and modifications dont support that much boost.

So the car in essence tuned it self "slower" via ignition. Thus it doesnt feel as fast.

Stay on map 5.

This is of course not seeing your logs... but im assuming your feeding too much boost for your octane and modification levels thus progressively going slower.

More boost doenst always mean more power... there is a point of diminishing returns via increased HEAT.
