cant control boost

[droptopgst]

OK for everyone that has not seen my mods here they are.

TDO5 18g turbo ported
Greddy Upper & Lower ICP
Type S BOV
Turbonetics B/C
Ported O2 and Manifold
3" ATR turbo back exhaust w/high flow cat
Boost gauge, Oil psi gauge

I have 660s, AFC II, EGT gauge coming monday.

No check engine lights, car runs fine just cant control the boost. It spikes to about 12psi around 4k then from 5500-6300 it creeps fast to 23-25psi then I let off the gas. Not sure how high it will go and dont care to find out.

I just hooked an air compressor to the actuator and it does move and opens the waste gate. Someone please give me some more suggestions I need to get this fixed.

Well I just put the new hallman boost controler in and my car is still boosting 25+. you guys have anymore suggestions? My afc and 660s will be going in this weekend, but still need to find the problem here.

I have the same problem with boost creep. I am trying to make an appointment at my local performance for monday for them to look at the problem. There is a guy there who has a pretty nice eclipse. I will inform you what he finds out (if he fixes it).

Did you port your stuff your self or did you have a know shop do it. I ported my own parts at first and took a good bit of but still have boost creep problems, so I sent the out to get redone and I have had no problems since. Well except from the damage I did to the turbo before I got it done right.


Good luck Matt

Sounds like the same thing thats happening to me, and its not boost creep. I think that my wg acuator is shot. I just tried to install my brand new joep mbc and i couldnt get any boost control, i couldnt even go half throttle under boost. I would try and take off the wg and hook it up to a boost source and see when it opens the arm.

Well, I have installed a new b/c (hallman) put all new lines and this has made no difference on my boost problem. I also did a leakdown test and there are no leaks that i can find. When I put the airhose to the w/g, it opens with 12psi. so what other things can I try here

Heres the update fellas- No more boost creep. I sent my turbo back and they clipped it and put the 34mm w/g and flapper in it. it holds nicely at 15psi, or at leat 4 now!
