I have an Injen CAI on my 2011 WRX. Throwing the CEL and it's too lean.
The closest custom tuner place is 500 miles away. I've heard the Hypertech tuner will fix the problem (not just turn the CEL off).
Does anyone know any other solutions?
I want a cold air intake, I do'nt want to go back to stock.
What other options do I have???
