Jakes and high boost?

[in2trux]

12,000 miles on the inframe, it's not broken in yet.
It should improve as the miles go by.

We've seen a steady improvement since overhaul in June, starting @6, 6.5, now 7, 7.5, 8 after 30,000. That's running 77-80k up and down the hills of PA,NY.

How it's driven from day one will have a long term effect.
Once you hit 100-200k miles you're getting into the sweet spot for mileage and power.
