Message 2011: stock cams & stock cam gears
2012: 400+ cams & stock cam gears
2013: 400+ cams & BDE 1st gen intake & Tomei exhaust gears

2011 (red) vs 2012 (blue):

Torque is gone between 3000-4500 RPM.
Got some top end gains, but without the adjustable gears, the cams could not be dialed in and it was a noticeable performance hit. Mixman told me... Greg told me... get the adjustable gears.

So the next year... 2012 (blue) vs 2013 (green):

Hooray... TQ is back! Top end minimal gains.

The takeaway:

- Stock cams and gears give good midrange TQ.
- Upgraded cams need adjustable gears for gains.
- Upgraded cams with stock gears = no bueno.
