Nice numbers OP, I think in terms of efficiency, your car will certainly benefit from doing a catless (or catted) downpipe.
Impressive if it was a mod other than a DP. Maybe the stock IC is why they are holding it back as there is a lot more available on the table with a DP than what is reflected in that graph.
