Addressing the EPA regulations with your modified Subaru.

On april 18th Cobb changed everything. Long story short Cobb Tuning removed a lot from their software functionality per EPA regulations and the software is now much different and more limited only supporting the areas allowed by the EPA. While the new software update limits some things we are still tuning Cobb AP daily and making great power! Cobb is also currently developing new CANbus based flex fuel kits among other power adding parts that will all fit within the EPA’s new regulations. We will be offering special pricing for all returning customers making updated modifications to best utilize the new Cobb AP abilities and Cobb’s green speed program.

Those planning to continue to use the Cobb AP will need to re install all OEM emissions equipment including TGV’s, secondary air pump and EGR. Please note while most people remove these parts there is actually NO need to do so. Non of these emission related items hurt or effect engine performance they are simply there to help keep the emissions low under normal use like idle and cruising conditions.
