dump dube, sm16g, 34mm wg mod... still creeps, please look.

I have been having the boost creep problem ever since i installed my sm16g. I recently got a o2 dump tube and a 34mm flapper. I installed both today and ported the wg hole very well. When eveything was done, i took it out for a drive, and wham... boost creep at 4500rpm. I mean i cant even floor the car in 1-3rd w/out it creeping up to 20psi.
I dont even have a boost controler hooked up(its running strait to the wg act.) I've read tons of posts and searched to see how people have gotten rid of or lowered thier boost creep, but everything i have tried has not worked. Is the only thing left to do is go external?

I put a hi flow cat in , and that slowed down my creep. Might wanna try that. Have u done n e other porting ? Try porting the mani. and o2 housing , mayb that will help.

i have everything ported. Manny, turbo exh inlet and out let, the o2 dumps ported and the wg flappers ported.
If i put a cat on i would have to get a new dp.

Here's how I got rid of a boost creep problem: I turned up the boost on the boost controller just a notch or two and the creep is only maybe a pound or two. Get an electrinic boost controller but you don't have to go crazy and spend tons of money. I know people swear by MBCs but I'm too lazy to get out of the car each time I need to make an adjustment. If you wan't to know what set up I have, go to my profile. If you need more help, swing up to the Gurnee IL. There are a few DSMers that will help you out.

Check that your wastegate actuator is working. Get a pressure source and test it on the bench; it should be fully extended by ~10psi and not leaking.

Id be willing to bet all you need now is a test pipe and you can finally say bye bye...
