The speedometer has always over cooked the mph, the car has never gone so fast and it has actually improved the use of the low end torque of the engine having a slightly bigger rolling diameter, in the corners there is not much that will touch it, even I have not found the limit to the grip it’s endless, track only now with plenty of runoff, as l think it will be more like a 911, it would be amazing if it is still a gradual brake away.
If you are going to keep it and want it to be reliable take the lot of put a new manifold on with a Holly or Webber, and then enjoy the Atmo, the most under rated GTA when it can breathe
