So I purchased a new 2016 sti last month and put 1300 miles on it all while properly carrying out the break-in procedures. Then started noticing oil spots under the car, lifted it up and sure enough it was already leaking oil from the turbo area. Took it back to the dealer and they replaced the whole turbo assembly under warrenty as the car is stock aside from axleback tips. Problem is, I'm now only hitting 11 psi max boost in all 3 modes. Any suggestions before I take it back to the dealer?
