Is it possible to get a boost leak after an oil change?
I took my car today to get the oil changed and TONIGHT, around 2am (hint hint colder weather ) I ended up going WOT on the onramp, and I noticed that my boost gauge wasn't holding at 1.4 bar steady, instead was going between 1.0 and 1.4 bar in a see-saw like effect.
My question: Could I have a boost leak as a result from them changing my oil at the dealership, or could it have been the cold weather giving me boost spikes.
