Here's the diagram of my setup.

That's how mine is rain too. Except I don't remember exactly which port is which on the EBC solenoid.

I actually did rerun all the line, they had it all messed up.

Also, when you tuned the BC off, did you leave the solinoid plumbed in the wastegate lines? Try completely removing the BC from the loop so you can be certain your wastegates are as isolated as they can be.

i have see about 21-24 psi... When I turned off my Profec the boost just went up and never blew off until I let off the gas and the BOV took over.

It would also be nice to see what you were peaking at.

I am going to try that this weekend, I wanted to do it earlier but many things came up. I have the three port and the drawings look like the way i hooked it up. I have the control unit hooked up to the big vacuum line from the manifold to the fire wall. I want to just check to make sure I put the line correct on the waste gate. I also don't see were i have a hot side line hooked up to the wg. I will have more info over the weekend! To bad no one live close they could have some beer and steaks to help me get it right!!

I know this goes without saying, but it really should be said because of the danger... BE CAREFUL! 20+ PSI you are in very dangerous territory if you aren't built/tuned for it.

I'd also probably get a compression test if you think you really saw boost over 20psi.

I hate to scare you but my motor was turned into hot glitter at 23.7psi. If yours didn't blow there's a very good chance there's some crooked parts inside. Not definite but from my personal experience I'd be wearing depends till I got compression checked. The wastegates have upper and lower ports. The upper is either on top where it says Tial or directly on the side of the top hat. The lower is the other. (Not the one marked H2O). The upper is connected to the charge pipe via Twitter connector. The lower comes from the port as I sent the diagram into a T. Try to keep the length from the T equal. I sincerely hope that you didn't bend a rod or tear up some rings. But on the bright side it's an excellent excuse for a built lower. I'd drain the oil to check for glitter and if it's there purge the exapump. ( Don't ask how I know.) If there's no glitter check compression. Also I have a Greddy and it's pure Voodoo. Set it up at the lowest boost setting and work up. Here's where mine was at 9PSI

Lo boost settings
SET= 24%
WARNING =10.5
LIMITER=5%
START=7.5
GAIN= GO SLOW AFTER ALL OTHER SETTINGS.

That should keep you safe but that was with 5lb springs and maybe lower the set boost to 20% and set the warning to 9.5psi . That's a start once you get the readings you creep up slowly. When you find exactly where you want to be you can play with gain but that requires a copilot and a long trip to Mexico in and out of boost.

BTW this is a simple wave off and budget approval if the better half can be convinced that it was a common spark plug issue. This has been tested and it works.

hc_416 · 05-03-2017, 10:37 PM

I do have a built lower end from aam, its that the wastegates are not workgin right and i have to figer out why...

solidus · 05-04-2017, 06:10 AM

Well hell you should be good then. I say pull the wastegates, take them apart and make sure they're assembled corretly, put in the 5lb springs and then configure the lines the way I showed you. Then set up your boost controller correctly. You said you plumbed all the lines again but did you use new silicone or reuse the old? If you used the old lines did you carefully check each line for holes. I had a small hole near the passenger side wastegate that caused that wastegate to remain closed. It was tiny but I imagine with 23+ psi it expanded enough to cause a ruckus. You're past the hard stuff this is just where it get's tedius and irritating because now you just want to spool.

jwick · 05-04-2017, 08:24 AM

Unless you only want to run 10lbs, you'll need more than a 5lb spring in the WG. I'd put at least the half bar spring, maybe one step bigger.

I will look again, I did not replace every hose, i think i reused two of them. I will go back and check. I will be taking off the waste gates this weekend, I have some time.

I am wondering if I swaped the hose's wrong. That is what I am going to check first. then I will take them apart after. Hey were do i get a BOV spring?

jwick · 05-04-2017, 11:07 AM

No clue where to get a different BOV spring.

I also wouldn't go swapping WG springs without a retune. You want to make sure you are tuned for the boost you'll run. Also have your tuner give you a map setting for just WG pressure and then a map for each of your EBC settings (I.e. If you have a low and high boost setting, you'll need a separate map for both).

Boosted Performance · 05-04-2017, 11:38 PM

PM your ship to address and I'll get a BOV spring shipped over to you.

hc_416 · 05-12-2017, 12:51 PM

THE BOOST CONTROLLER IS BROKEN!!!! I BELIEVE THAT THE SOLENOID IS BROKEN/FROZEN. I hooked up the wastes-gate with no boost controller and it worked fine and only boosted to 7 psi. So Do you guys think I should buy a new solenoid, or try a different brand? My brother said that BC is a troublesome and not worth the problems. Any ideas or suggestions? I am also just waiting for the BOV spring to get that right so next week i'm hoping to be close to the new tune and ready to rock for the summer!!!
