Cold weather and boost spiking??

[meet07]

For the last 3 days my car has been creeping up to 12lbs of boost and cutting out. I thought it was my boost controller but I removed it and ran the hose straight from the hot pipe to the wastegate. Took the car for a spin and it spiked again. I mean its been around 15-40 degrees here in Raleigh,NC but I didnt think that would cause an extra 5 psi. Is my wastegate defective?? I havnt meesed with it so it should not be bent or anything.

has anyone had this problem before??

on average is 85degrees F here on my island and at night ...mid to high 70s. running off the waste gate i get 8psi during the day and creeps to 11 at night might be more dramatic here since i'm at sea level..

Whats your w/g location? my car used to creep during cold weather.

im running a factory wastegate with the factory turbo. When I had my turbo da9 b16 I would see maybe 2psi increase over the cooler weather but nothing this drastic. Could it be b/c of the smaller turbo or do I need to clean/lubricate something on the gate?? Its prett agravating

its 100% normal, on colder days your going to have more psi because the air is denser. like right now im running 11 psi, and when its warm i run, well i really dont know because i havent had the car running during the warmer months. but i have friends that have boosted cars and they are running more boost when its cold.

Yeah I know that but an extra 5 psi??? That pretty much means the car is pointless to drive during the winter.

what kind of boost controller are you using?if you say manual thats the problem right there.

I thought it was my boost controller but I removed it and ran the hose straight from the hot pipe to the wastegate.

Did the same thing when the controller is not connected...

mine does the same things, everything stock, spikes to 12-13psi on cold weather, i say normal, doesnt cut out though

[meet07]

so should it boost past 12psi without it cutting out?? If so I need to look for boost leaks I guess. The temp over here in nc went up a lil and everything is back to normal. I was just stumped on the whole spiking issue. I guees the smaller turbo and toques causes it to spike more than my integra. But then again it had a external gate.
