BWR manifolds have been known to creep. But it sounds like you need a 4-port for such a small spring. A 4-port solenoid will force your wastegate to maintain better boost levelsQuote:

Faulty manifold design. A 4 port solenoid isn't going to fix the problem.
Still a buster.Quote:

Actually, that's not necessarily true. It could be a minimal boost leak from a coupler, incorrectly routed vacuum lines, or something else to that matter. So you have a few options to see what's going on. Let's begin diagnosing. What's your vac line setup?
That's a great topic ill start a thread on next vac routing diagram!!!! Thanks pal.
Many people have had issues with creep for having too small of a wastegate spring. It could be quite a few incorrect factors, and doesn't necessarily mean it's strictly poor manifold design.

The only thing that causes creep is the wastegate and it's related parts. So if the vac line going to the bottom port if the gate has a leak, you may see some creep. If there is a leak in a coupler you would actually lose boost not creep above wastegate. If the lines were hooked to wrong to the wastegate you would creep so instantly to boost cut it isn't even funny (has happened to me when I was making sure my lines were hooked up correctly way back when I had serious boost creep issues). Another cause although unlikely is the diaphragm in the wastegate is torn. But I would say it's damn likely it's the manifold if many people have boost creep issues on that manifold.Quote:

A small wastegate spring doesn't cause creep. If it isn't creeping for someone on a larger spring it just means the creep is being somewhat offset by the larger spring. Basically a small spring really tests the manifolds design to see if it can flow well for power and still have very good flow to the wastegate for proper boost control.

Im running a 10psi spring.
I might as well give a little update.
I brought my precision 6265 DBB turbo to WCF so Precision could take a look at it. The exaust seal was leaking i guess, so they kept it. I received it back in 2 weeks, 200 bucks TOTAL (including shipping to canada) for a complete tear down, rebalance, seals, cleaned and a new restrictor inside. I was amazed with how it looks.

No shaft play. Im excited to get it back installed and running.
Picked up a DEI turbo blanket for 80 bucks at WCF

and got one of these.

but of course, i need to delete my power steering because the runners come in contact. I grabbed a karcepts ac/ps kit. Next is to sell my id1000 in favor of some 2200s, and find a twin disc.
Id like to get 600-650whp this year and run some mid 10s. Id be extremely happy with a mid 10 second street car :P
