I was just wondering if having ESC reduces acceleration and top speed in a straight line not during cornering because I know it does there if you start losing traction.

Example : I floor it from 65mph and once I hit 90mph it accelerates extremely slow to 91, 92, 93 etc... If the ESC is off will it accelerate faster at these speeds.

I also have a 2003 Hyundai Elantra which is less powerfull with like 160hp but it's a lighter car and it accelerates 0-90 faster and from 90 it can get to 94 (fastest I've driven) while the other car can barely hit 91 let alone 94.

So does ESC slow the acceleration and top speed of my car???????
