It's hard to know for sure if you damaged your car by driving 80 MPH during the break in period. The effects, if any, are probably pretty small though since we haven't heard about other owners having major problems from this.
Driving slow during break in almost certainly won't limit the top speed since that's controlled by the computers. You're not allowed to approach the "real" red-line of the engine.
