Exclamation Do I have boost Creep in my STI?

I currently have a Helix Catted DP and Borla Hush Exhaust. I am running the Cobb Stage 2 program. I don't hear any weird sounds, and my boost gauge never goes higher than .11 boost? Is there anything that I need to worry about?

Could you take a clip of your exhaust? Thanks I'm about to b uy that setup as soon as I finish getting the money.

are you holding consistant boost levels? have you ever hit fuel cut? do you see the boost hit a certain psi then drop and raise back up?

Fuel Cut?

From what I can tell, My boost stays pretty even. I don't seem to notice what feels like fuel shut off, would I easily notice it?
thanks,
B

I have been encountering a similar problem. I am hitting the high boost from my cobb stage 2 but it sounds like my bov is leaking. most of the time the turbo tone is steady but in hard driving I notice a sound that seems to be the bov venting. as for your boost creep try (if you haven't already) changing the base map to what you want and not the realtime map.

Cobb Stage 2

I just put on 91 octane Base and Real map and put that on there. How would I do it differently? Also, wouldn't boost creep make a noticable knock or ping?

if you hit fuel cut...you will definately know it since it throws a CEL. It will have kinda a instant jolt feeling where it's resisting....plus scare the **** outta you. From what you describing, it sounds fine so no worries man.

Yeah, boost creep is like female orgasms... if it happens, you KNOW. If you're not sure... keep trying.

Talking Awesome.

The STI must be for my pleasure only, because she isn't making any noticable sounds or screams!

haha in a way thats kinda right....if you wanna keep trying, do some freeway pulls starting at around 50 mph in 5th or 6th gear and keeping accelerating to see if it creeps.
