The 2 degree earlier EO and 2 deg later EC will not make as big of a change as you might think. The smaller exhaust makes the converter stall a tiny bit less critical. If you moved the ECL out 2 degrees on the bigger exhaust (+1 LSA) the overlap would be the same and it would make more positive difference high, but with more penalty low.



Where are you on PTV. I can help more Tuesday if needed…
