Just got a VF39 installed on my 05 WRX. With the stage 3 COBB tune and all the supporting mods. TB exhaust, intake, ebcs, injectors, STi Intercooler, etc. it runs pretty good for an OTS tune. Pulls really good too. The only complaint I have is it peaks boost around 21-22lbs. COBB’s notes said it peaks at 18lbs. Not sure if it has anything to due with the wastegate or not. If anybody wants to chime in on what they think that would be great.
