Engine oil flow

The spring that people shim is for the relief valve (or bypass valve) for the oil pump. This diverts oil from the pump should the pressure exceed specifications. I'm sorry, I don't recall all the details. It's been covered on SM and SF in depth though... possibly here.

The physical installation of the MAFT Pro isn't too bad at all. Setting it up in MAF translation mode (which is where you would replace the stock air flow meter for a less restrictive, larger diameter Mass Air Flow sensor such as the 3.5" LS-1 GM MAF) isn't terribly difficult. Setting the system up for speed/density (which removes almost all intake restriction) can be a bit tricky and sometimes hard to get get "just right". This system grants you a LOT more control over your vehicle than any other individual piggyback. In my opinion, it really bridges the gap between piggybacks and complete standalones as far as what it offers.

Here's a little more specifc info, keep in mind that this thread is for people with N/A's looking to add a turbo:

Here's a list of all the settings in the MAFT Pro v4.80 software:

This list may have some inaccuracies, but it'll give you an idea of what you need to learn if you choose this route.
