XPT Stage 2 - 08-09 EDM STI

$135.00

This particular map is designed for the 2008-2009 EDM Subaru WRX STI with the following modifications:

-Stock Airbox with K&N Part # 33-2304 or
-AEM Cold Air Intake Part # 21-478WR
-Catted or Catless Downpipe (Invidia Preferred)

Further instructions will be provided upon receipt of your new map. This will include details and proper map break-in procedures/tips.

Target Boost for the K&N Panel Filter map is 21.5psi in 4th gear which will taper down by redline. 3th gear will see around 20.50psi. 5th and 6th may see closer to 22.5psi which is perfectly normal. Air Fuel Ratios should be around 11.2:1 during spool, 10.8:1 in mid, and 10.5-10.8 by redline. I highly recommend monitoring the Air Fuel Ratio with a wideband o2 sensor such as the AEM Uego, or the Innovate LC-1 if available.

Target Boost for the AEM CAI map is 22.0psi in 4th gear which will taper down by redline. 3rd gear will see around 21.00psi. 5th and 6th may see closer to 22.50psi which is perfectly normal. Air Fuel Ratios should be around 11.5:1 during spool, 11:1 in mid, and 10.6-10.8 by redline. I highly recommend monitoring the Air Fuel Ratio with a wideband o2 sensor such as the AEM Uego, or the Innovate LC-1 if available.
