I know A LOT of people aren't hitting the advertised boost on their Si, but I bought my car a few months ago (new with 30 miles) and I was hitting 15-17psi and its been gradually dropping to where I'm getting 12-13psi now. I called the dealer today to tell them my situation and they were less than helpful. Off the bat the service advisor said "so you were racing your car and blew it up" and later in the conversation "so who were you racing when you blew the turbo". He called me back after talking to a tech and said "First of all I don't understand how you are measuring a boost pressure" and I had to tell them that the car can read boost on the cluster.. Anyway the tech is blaming the issue on "winter gas" saying that it has lower octane and lower octane = lower boost and that if I had a leak that I would be losing a lot more boost. I didn't realize that only hitting 60% of your boost was not low enough to constitute having an issue. They told me to put octane booster in my car to see if it helps and if not then they'll schedule an appointment for me. The only mods I have are a different muffler (cut it off and welded a new one), short shifter, CDV removal, and an intake. I took the intake off to see if there was any difference and I was actually hitting about 1psi more with the intake on (13-14 instead of 12-13 with stock intake). The advisor called me back again and left a voicemail with more excuses saying that the built in boost gauge is inaccurate because it's electronic and not getting its reading from an actual vacuum source, and the car has an electronic wastegate and the ECU will limit boost in cold weather to protect the turbo because it gets very hot and I have to be driving for 20-30 minutes for the oil to be at operating temp, et cetera. What do you guys think? Car has 5k miles and I have a lot of knowledge and experience with turbos and manual cars, and a little experience with tuning.
TLDR; boost dropping from when I bought the car, only getting 12-13psi. Dealership is being arrogant and giving me excuses and now trying to say its normal.
PS I have the voicemail saved if you guys care to hear it I might be able to upload it
