Here is the deal. Tial 38mm wastegate with a 7.43 psi spring, Greddy Profec B boost controller. All my vaccum lines are properly hooked up, the problem is with the boost controller set to off I boost rigtht away to my cutoff, which is 10 psi. With the controller on, at the lowest boost setting, I also boost to my cutoff. What the hell is going on here.

Someone has to know.

Thanks in advance guys

 

this happened to me with my profec B but when i had it shut off so it ran off the wastegate spring, i had the vaccum line running to the wrong port on the wastegate. on my tial 38mm wg, i had the vaccum line running to the side port instead of the top port on the wastegate. also, make sure you have the wg line tee'd into the line running from the compressor housing back to the bc soleniod. hope this helps, call greddy if that doesnt work, they told me exactly what to do.

 

thanks, ill give it a shot

 

now I'm really screwed up. I completely disconected the profec so I can run off just the wastegate spring and it still spikes like there is no tomorrow. What the hell is going on.

Could it be my drag manifold?

I need some ideas guys

 

someone help me out here. Please

Anybody?

 

I have that same problem with my tial 44mm gate. when i use a 6.5 psi~ I get ~ 9psi. now when i go to a combo that should be around 14.5 psi , I get~ 17.5 psi. this is with a Full-Race manifold (old style), and profec type-s BC.

 

this is how mine is hooked up if it helps any...it works fine by the way

 

I dont have a line running from my solenoid to the turbo...?

 

definately hooked up backwards.
my directions that came with the boost controller had me hook the wrong hose to the com port on the solenoid
i will take a look at how mine is hooked up on my 44mm and let you know tonight
but when mine was hooked up wrong i was boosting 15psi at 4000rpm with the boost controller off with a 7psi spring in my wastegate

 

all of my vaccum lines are hooked up properly. im out out of ideas

 

maybe you have them hooked up on the wrong ports on the soleniod....try swaping them?

also how long are your lines and what size

 

the weird thing is, when I first got t he controller everything worked fine, for about 1 month
