OK, so I dont know if it is my turbo, boost leak, or my gauge, but I was driving home from work and I decided to floor it and the thing shoots up to 30psi? I am on the GMS1 tune and all the mods i have are below in my signature, please help i need some advice.

 

A boost leak generally causes loss of pressure. I have seen 25-26psi on GMS1.

Other than that, could be the system not release pressure.

Might check the BPV and make sure it's not stuck.

 

maybe cause i let it sit for ten minutes or so, did another a couple of pulls and now everything is back to normal, i jiggled the vacuum hose going to the cai but that hasnt been touched since i installed it. i hope the BPV didnt get stuck open guess itll mean i have to buy a new one lol

 

If it doesn't do it again then I wouldn't worry about it.

 

true if anything ill just by the forge BPV

 

Could be the waste gate actuator, tubing to the waste gate, waste gate solenoid, or waste gate rod.

 

it did it again today, i notice it happens when the car sits for a long period of time, another than that its fine, only happens with a COLD start...any suggestions? i dont get on it until 199* Coolant Temp

when im driving i just keep tapping the gas a little and it fixes it self boost gauge would go up to like 30 then after feathering the gas a couple-few times it kicks back to normal at like 20psi
