Glad to hear you've finally had time to get this going. I'm sure you have been itching to see the differences in the tuning and how it would affect the truck performance.

In regards to your data, that is excellent information! Very nice improvement on the 0-60 and 1/4 mile times, especially since the EGTs are holding 1100 Deg. 22 PSI on the stock turbo is a good number as well. Overall, everything actually looks really good and right in line with the results we'd expect. Only question I have that I didn't see already answered was the weight of the vehicle. Don't know if you have a scale sheet handy, but that would be useful as well.

It does sound like you might have reached the limits of the clutch. It happens. Several good options out there for heavy duty clutches and pressure plates. I'm fairly certain that South Bend Clutch can get something together for you that will be able to handle the torque output.

Looking forward to some fuel economy information as you have time!

Take care.
