After over a year since the EPA banned all Flex Fuel systems for Subarus. Cobb tuning has finished developing the Subaru NexGen Stage 2+ Flex Fuel Power Package for the STI.


NexGen Power Packages re-establish the modification and upgrade paths for supported vehicles that have been impacted by the removal of Downpipes. These packages provide similar performance and excitement, while maintaining legal emissions standards.

The Accessport is the world's best selling, most flexible, and easiest to use ECU upgrade solution for your Subaru. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Follow our staged upgrade path with pre-loaded Off The Shelf (OTS) maps or use custom mapping for any modification level. It's the last engine management solution you'll ever need.
