What exactly happens when you " race " on the highway? check your intake manifold if there is any oil, then check your intercooler pipe that connects with the turbo. if there is oil in the intake manifold its your rings.

It´s most likely not the valve stem seals since their sympthom is showing up at startup witha blue puff out the exhaust.
Under boost it´s either a very rich condition (black smoke-unburned gas), piston rings or maybe turbo seal(s)..
Just my 0.02

I would also do a leak down test if you think your rings may be the problem.
