2008 STi Maps

1.01 - Revised Boost Limits parameters, modified WGDC tables to avoid boost creep in higher gears, and increased authority for the boost control system to make corrective adjustments.

To use any map off of our website you need to make sure you are using the most recent version of AccessPORT Manager and you need to have firmware 1.2.X.X or higher on your AccessPORT. You can check your firmware in the About menu on the AccessPORT. If you have older firmware, here is a link to the most recent firmware:

Firmware 1.2.6.X

Those of you that are having over boost issues, try the new 1.01 map and report back with how the car is performing.
