Assuming that's the line you tapped for your BOV yes.
Torque Booster Kit - only 8 PSI

For those of you with belt slip...how does your boost gauge read? Does it peak with RPM (redline) or at a certain PSI? With the 11.6 WG spring, mine would peak at 9 psi at about 6500 and stay at 9 until 7500 or redline. Almost as if it's being bled. I switched back to the 9.7 springs and it's now peaking at 8 psi. I'm wondering if the WG is bad.
That will tell you right there. I bet you get more than 9 psi
Whats your car dyno at before and after the torque booster?
I never dynoed or taken it to the track.
That's how mine is peaks at 9.4 @ 6400 and holds that till red line. That's what it's supposed to do. If it was belt slip it wouldn't go past 8 when you put the bigger springs in. You can try the 13 and see if it goes up again which if it does it's not belt slip.
Are you 100% sure you have the right springs in?

That's how mine peaks which leads me to believe it's the WG. Just be sure I googled the spring chart to check for consistency and made sure to put the right springs.
Yes, mine had that same chart included with it. I assume its the right one.
So I completely removed the WG setup and put the stock pipe on. Made a pull and it peaked at 9.5 psi. I checked again for belt dust (cleaned it with simple green a few days ago) on the balancer, by the headunit pulley, and the pulley right below the headunit pulley. Previously I had a lot of accumulation on the balancer and the pulley right below the headunit. I found zero dust on the balancer and very small amounts of regular dust (not as dark as belt dust) on the pulley below the headunit. There are definitely too many variables (hot weather, less exhaust restriction , etc...) and the fact that boost pressure is only a measure of restriction as previously mentioned. I'm going to data log and send it to Lund to see if everything is ok. I might just drive it like this and keep the wastegate setup in case boost creeps up in the winter or just sell it.
Did you swap back to a larger pulley as well?
if your only seeing 9.5 with the 3.33 something is wrong, you should be seeing 12-13 psi with that pulley
Something is off still then. The 3.3 should be making 12-14 psi.
Edit: Treed by Beef.
Don't know what else it could be. I've been doing a lot of reading and some cars are losing anywhere between 1-4 psi just losing the cats. They were all different cars.
I got to 8psi with the 9.7lb springs, 9psi with 11.6lb springs, and 9.5psi without the WG setup. So this can't be belt slip. Checked for belt dust too. Got any tips?
You are not loosing that much boost with just cat deletes. With a 3.33 pulley and no wastegate you should be atleast seeing 12psi.
Just as said before, boost leak or belt slip.
