It is a H box that has APR programming

Mode 1 is stock
Mode 2 is 91 Oct program 307hp/366lb-ft
Mode 3 is 93 Oct program 318hp/382lb-ft
Mode 4 is Valet (no boost and rpm limited iirc)

You can easily move between programs using your cruise control stalk

It also has fault code erase and throttle body alignment feature

and it has Anti-theft/Security lock out added which is a great feature cost me over $200 alone to add this. It allows you to enter a unique access code to disable/enable starting the car. You can enable and disable it using your cruise control stalk, very easy and quick to do.

When you buy APR ecus even used you can get updates for free (other then tech time) or change programs like add a race gas program in place of another program, at any authorized APR dealer.

If you also have an H box I would be looking at $400 plus you ecu in trade. Other letter boxes might work but i need to do research on to what works and what doesn't.
