High Boost Creep

[1glaserturbo]

I just recently had my local DSM shop install a 3" o2 housing back exhaust with the stock o2 housing. I was holding a solid 14 psi on the stock 14b before the exhaust upgrade but now it's spiking way over 20 psi. Well, in fact, it's topping out my boost gauge (30-0-20 Autometer Phantom) I'm not sure what I could do to help "cure" my spiking problem. This really only happens when I go WOT but if I slowly get the rpm's up there it will level out, sort of.


Any help is welcome, thanks!

boost spike = boost initially shoot past the setting then immediately settles back down to the setting.

boost creep = hitting the setting first then slowly rises as rpm increase.

I suspect you have boost creep not spike.

Yeah sorry, that's what I ment.

S'pose that's your answer then. Boost creep. There are more threads on this than you can imagine. And most of them start with "so I got a new downpipe..." Have a look see and you will get what you need to fix it. Not a super big deal, just do some porting.

BTW change the title to boost creep instead, it will make searching easier for others in the future.
