rather than reading through all 600+ pages that talks about his tune could someone be so willing as to break it down why his tune is better than what comes with the sct x4?

Thanks in advance

SCT calibration is fairly conservative but that isn't the worse thing. The tune assumes you have a stock car and may have some headroom for bolt-ons, I can't confirm this others may.

Why not read all 600 pages you might learn something, I certainly did.

You will need a tune or at least an edit to your base tune for -

Cat-less down pipe, ethanol blends and additional exhaust flow

If your running strictly pump gas then you'll get more timing if you upgrade the inter-cooler, you also might get more boost.

On top of all that, lifetime revisions come with your purchase of a custom tune.

Because it's built specifically for your car. As opposed to the SCT tune which is one size fits all. Torrie looks at how your car is running on the tune and makes revisions custom tailored to your car.
