Although when I gave it full gas from the start it sort of like bogged like it was going to accelerate then the throttle shut off a bit then accelerated back again. I had good smoke and the temps stayed the same so to be safe I just set it back to 3 hours. Could it be that the LSN needs tuning now?
Sounds like you are now to lean on the HSN. Open it back up 1 to 1.5 hours from your 4 hours leaner and run it. You were experiencing what sounds like a lean bog. It could also be that you are not fully broke in yet and there is still mechanical pinch causing the temps to climb. and if you haven't read it yet read the engine tuning bible at the top of the page.
