So Jim is out of business.....interesting.

AZ Speed did a reprogram on my MEFI3 when the Whipplecharger was installed. He inserted a custom aluminum adapter with an O2 bung between the riser and the exhaust manifold. I think he did a decent job on the program because EGTs and plugs look good and I don't get soot on my transom. Unless you can improve upon what he did, I would rather leave the spark and fuel curves alone. Although, since the first reprogram, I did change to heads with 2.30" intakes.

Now the million dollar question.....
Is there any torque left in my setup above 5000 rpm??? Maybe I shouldn't be running there in the first place.
