If you have a TR8 that seems to have a slight surge or hesitation while driving down the road and you still have the stock intake and exhaust manifolds, here is how to fix it.
Simply find the hose the runs from the EGR valve that is Located on the exhaust manifold.
You can remove this line from the egr valve and do not have to cap the actual egr with anything. Now follow this line up to the intake. Once you find this you can now cap the line that runs to the intake. You can see in this picture it was done with a screw.
Now you should be all set for a nice smooth surge free ride down the road.
