So first of all, my car is an 03 WRX. Completely stock except for an AccessPort flashed to Stage 1 91 octane. I have the AccessPort mounted to the side of the wheel and I use it for a boost gauge.
I was driving home tonight and accelerated pretty hard in 4th to pass someone on the highway and right as I was passing them I glanced over and saw that the AP was reading 16 psi. Later, I had to pass someone else, this time there was less room so I went to 3rd gear. The car pulled strong and smooth... felt great, but after I was around the guy, the AP said I had hit 17 psi.
That's more than a Stage 2 WRX should be hitting, right? I thought that Stage 1 was supposed to hit 14.8 and Stage 2 was 16.5. What's up? Is this something to worry about? I was planning on putting on a downpipe and going Stage 2 in a couple days but I don't want to do that if something is wrong...
Edit: The one thing I thought of is that I am at ~7000 feet. It's considered safe to run higher levels of boost at higher altitudes, right? Could the "learning" function of the ECU be kicking in here and upping the boost?
