RRE tuned a 2009 WRX to 270HP and 302TQ! The car was previously using a Cobb Stage 2 map (map came in around 235HP, per RRE). Mods: AEM intake, Catted downpipe, cat-back exhaust and 3 port solenoid. The car gained + 58HP and +51TQ at 6050 RPM.
Crazy. Note that they do e-tunes as well. I might try this, since I trust them…been to their shop before and have met some of their crew – Mike Welsch, Scot Gray (dunno if he’s still affiliated with them) and a few others.
