FlintGTS

dealership damaged some piping when replacing water pump.

My water pump was found to be leaking fluids and was replaced during the service so the likely cause too...

It was a major headache. Mine is still not fully resolved. My boost is a couple PSI short of 18 now and they have had the car for quite awhile trying to figure out why.

i'm happy to report that the leak has been found and fixed. Turns out the "Porsche Specialist" that installed the BMC filters didn't tighten the inlet clamps. I could tell from day one that it had a lesser leak(you can even find an old post of me asking if its normal) and when I asked i was told that it was due to the filters breathing better. I can say now with 100% confidence that the car has never performed like this since I've owned it. I thought it was a beast initially after the tune/filter upgrade and it was but it is now a completely different car. Sounds better and oh my, the power is just scary. The car was sitting on a lift for 2 months since buying my Tesla M3P+ but as of last week when i got the GTS back i have not driven the Tesla once. My consideration of upgrading to 3RS is now completely out of the question. So for anyone reading this, if you get your filters upgraded and hear any type of air leak/seep you should quickly have them check the inlet clamps. You should hear no air leaks whatsoever.
