Yesterday I was driving home from the store with my girl and she was wondering why my boost gauge stays under 0 psi on cruise.So I explain to her and show her when I make go above 0 psi and I was in fourth gear and must have been like 40 mph.I floored it and showed her when it boosts and my boost went past what I have
it at which is 23 psi.It went to about 25 to 26 psi.I let go of the gas quickly and was just stunned.I have never went past 23 psi.Was it cuz I was at a very low rpm and thats why boost went so high.I floored it before on fourth gear and it went to like 23 and a half then started dropping off as rpm climbed. Can anyone explain to me why this happened.I'm at work right now and this just won't leave my mind.It's slow right now so I'm on the net.Oh yeah I have a greddy exhaust,aem intake,defi boost gauge,and dejon mbc.Later today after work I'm going to adjust the manual boost controller and see whats up.I would really apperiate anybody's input about what happened to me last night.

 

Happens to me if I mash on it when not at the ideal rpm for the gear as well. but it tapers right back down. Colder weather to! You should be fine!

 

when it gets colder you need to turn your MBC down. Cold air is denser, so if you set it in the summer, it'll be set for thinner air and will actually let more boost when the air gets cold.

Yet another reason why MBCs suck IMO.

 

do you have a downpipe?
theres nothing really to worry about though. these cars can handle 27 without any issues, but if it passes that I would be concerned

 

I don't have anything else on there yet.I have a ams test pipe that im going to put on this weekend as soon as I get one of those o2 simulator so I don't get a check engine light.
