I know this topic has been covered many times, but I'm curious to know how 2012 WRX owner's are breaking in/have broken in their WRX. I received the car with 7 miles on it and I've clocked 980 miles. I usually keep it below 4k and when I do a pull, the shifts are between 4 and 5. I've noticed a couple things. inconsistent boost, and what sounds like a release of pressure when I let off of the gas after a fairly hard pull. Im guessing that is normal, but I'm going to have the mechanic run diagnostics when I take it in tomorrow for a 1K oil change and boost gauge installment.
Any general education advice is appreciated, as I am new to the Subaru world.
