Thank you so much. Going to try this as soon as I get back to the car.

This seems to be what procharger does also. This is what they hook there pressure release valve up to.You can hook it up like Patrick did, I did it the exact same way back in 2015 on my single turbo kit.
For the twin kit I installed a vacuum block to make easier for additonal boost reference points in the future if needed (meth injection, electronic boost controller, etc.).
Would love to know what the purpose of that line is. Seems like with the throttle shut it lets air into the manifold. Maybe for idle? Why run it all the way back to the brake booster? Seriously can not for the life of me figure out why it's there in the first place.Well I think you all have answered my question. Looks like we left a vacuum line completely open thinking it was a vent hose. I definitely feel like a fool.
Same, we assumed it was some sort of vent that opened when letting off the throttle or something along those lines. Especially because it dumps into the air box before the throttle body and not after.Would love to know what the purpose of that line is.

It looks awesome!Realized I never posted any pictures of my completed setup.
Iām using ā13 F-150 turbos as well. I did not upgrade them and Iām using the stock wastegates. I drilled and tapped one compressor housing and ran a line to a TurboSmart boost tee (currently set to minimum setting). From the boost tee I used a t-piece and ran a line to each wastegate.Iām currently tuning with MPT also, as a matter of fact pretty much finished besides sending a data log for new down pipes after they are installed to make sure nothing major changes in the tune.
Which turbos and wastegates are you using?
Iām using 13 F150 turbos (upgraded), with turbosmart 5 psi wastegates preloaded with a hand held mighty vac to 8 psi.
Where are you sourcing the wastegate pressure line from?
I drilled and tapped my compressor outlet and sourced my wastegate lines from each turbo compressor housing. I donāt run a boost controller, just 8 psi wastegate pressure.
At wot my pressure holds 8 psi to redline, and 0 to vacuum at cruise.
I would highly suggest getting the hand held might vac that does both vacuum and pressure (yes there is a vacuum only model). This way you can apply pressure to the wastegate actuator precisely to make sure that both wastegates are set and working properly at same psi.
Are you using stock f150 wastegates? I don't think adjusting the nuts on the wastegate will help. Those should be adjusted until the valve is shut and then a turn or so for preload. If you are using a manual boost control some have a little spring and ball valve that will blead some boost even when the dial is set all the way down. You can unscrew the fitting and remove the spring to stop it from happening. Keep your boost reference lines as short as possible.Hey guys, new question (and sorry if itās been asked/answered, Iāve searched for 2 days and couldnāt find anything). The vacuum leak is fixed and they car is driving pretty good on the 3rd version of the tune from MPT. We are at the WOT section of the data logging process and Iāve run into a snag.
As Iām sure most of yāall know, the safe boost for the EcoBoost twin turbo setup is 8-10 psi. Well after hitting 14+ psi at 3k RPMs, I stopped, and adjusted the wastegates as far as I could without making the actual valve loose (to be clear, I threaded the nuts almost all of the way DOWN the shaft, pushing the rod INTO the part of the wastegate that connects to vacuum). I donāt think this was the wrong direction, because there is noticeably less boost during normal driving and at the lower range of RPMs. Unfortunately Iām still hitting about 14-15 psi during the WOT runs once I get to the 4-5k range. Iāve stopped and reached out to MPT, but Iām wondering if anyone here has any suggestions.
I have triple checked that my boost tee is set to the minimum value as well.
Yes, Iām using the stock wastegates. Adjusting the nuts definitely had an effect on the boost pressure. MPT and Tom from Super Six were the ones who suggested adjusting the nuts. Prior to adjustment I was making 14 psi at about 2.5k RPM. After adjustment I havenāt made 14 until about 4-5k.Are you using stock f150 wastegates?

You said your using a boost T. Is it a turbosmart? If so check out this link.Yes, Iām using the stock wastegates. Adjusting the nuts definitely had an effect on the boost pressure.

I will try this on my lunch break today. Thanks for that. I knew you could remove it, didnāt realize it adds 5-7 psiYou said your using a boost T. Is it a turbosmart? If so check out this link.

I upgraded to turbo smart wastegates and replaced my 5 lb Springs with 3 lb springs and removed the spring and ball from my Boost t and I'm still making about 6 lb on the lowest settingI will try this on my lunch break today.

Any idea if the TurboSmart wastegates fit on the 2013 turbos? Everywhere Iām seeing says they only fit on 2011-12 F-150s.I upgraded to turbo smart wastegates and replaced my 5 lb Springs with 3 lb springs and removed the spring and ball from my Boost t and I'm still making about 6 lb on the lowest setting
