Why are they limited ???
How is this limiter removed or altered
I think they are limited to make it easier and safer for the law to stop you since its not much over the national speed limits.
But most good tuning company's advertise speed limit removal, most modern cars can be done via the ecu to set the limit to a higher point.
But complete removal may allow the revs to redline which isint good neither so the limit would need to be set to a point that is good for the revs and the engine, which any good tuning company with a dyno rolling road could perform.
