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

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.

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).

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

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!!!

If you are going to be tuned with EcuTek you don't necessarily need a bc. Some are running without one. I would talk to your tuner.

You'd still have to have some kind of solenoid even if Ecutek is controlling boost. I know Ecutek can do it but I've never seen details on how exactly it works.

Hotrodz · 05-12-2017, 02:02 PM

I agree! I know it has been done and I think Hojin was setup that way. I think Seb has setup a few as well.

I went with the old Profec I bought NIB off eBay. Nothing fancy but tried and true. I've never heard anything bad about a Profec. You sure the solenoid is hooked up properly?

I have the same one he does, pure voodoo to set up.

Not mine. Other than being in bars, it's just High/Low/Off
