Hello!
I recently purchased a 2013 MS3 with 76k miles on the clock. The previous owner claimed to have done a full Cobb stage 1+ on the car, but upon further inspection, I noticed the turbo inlet pipe was stock and the airbox shroud was not installed. It does have the rear motor mount, the cone filter and pipe, and the HPFP internals installed. He would have done this about 3 years ago I believe. Was the Cobb stage 1+ a different package at the time (did not include the inlet pipe and airbox at the time?)
Regarding KR, I changed the gauges on the access port to monitor some things I wanted to monitor, and noticed that when feathering the clutch into 1st or 2nd gear, my KR will peak into the 2.5-3 range. The KR remains dead 0.0 on a WOT pull. This is relatively inconsistent; it will range anywhere from .5 to 3.0 at peak. Could this possibly be ghost knock due to vibrations from the rear motor mount being stiffer? Or is this something to worry about?
Regarding LTFT, I noticed that at Idle it generally stays around +8.5 and peaking at +9.5, but during a WOT pull it is 0.0 flat. Could this be caused by the Cobb stage 1+ tune being applied without the inlet pipe being installed? Or should I be worried about a vacuum leak and smoke test my intake?
Given the inlet pipe is not installed, would it be possible to safely load basemap on the car and see if the problem values go away, or would I be risking boost creep due to the Cobb cone filter and pipe?
Also, I have one step colder NGK Iridium spark plugs on the way that I will gap to .026 to see if that resolves the KR Issue. If it does, Ill update the thread.
Sorry if I sound like an idiot, I'm young and this is my first forced induction car, learning a lot but still a lot to learn haha.
