Also this will allow for reflashes at a reduced rate (100-200) when things like headers or cams are added.

This may or may not be a logical step. Headers bolted up to a 4 cat single exhaust may not see all that much gain. You have to remember this car had a very free flowing exhaust. Once we can do our own testing we will have more concrete input.

The only thing one can gether from this graph is that they will make power, how much is hard to say.
