If you are reading this then more than likely you have the same problem that i have been dealing with for the past year. That is that you bought an aftermarket LICP and installed it. Then 'T'ed into the hose from your BOV to the Intake manifold. So then you notice that if you WOT there is no problem, but if you try to slowly build boost or try to hold your boost above 7psi but not WOT, then you get a BOV flutter and you lose all boost in a matter of seconds.
Well the reason is because you 'T'ed into the BOV hose and the bleeder valve on the MBC is releasing air.
OK let’s skip the turbo lesson and just fix the problem. Now this is what I did to fix it, I took the advice from another EvolutionM.net member, I did what they said they did and it worked. So I thought I would share with a How to.

First go out and buy some supplies. buy Red Loctite, a 7/16" Drill bit, a 1/8" NPT Tap, and a 1/4" ID Hose Barb X 1/8" M NPT Solid Brass Fitting (it sounds confusing, but go to your local hardware store, they should have it).

Here are the steps; Pictures are attached below, in order

1. Remove the Aftermarket Turbo outlet pipe (Part of your LICP)

2. Mark a hole on your Aftermarket Turbo outlet pipe, in the same place that your stock nipple is located on your factory turbo outlet pipe.

3. Take a punch and a hammer and center it on the mark you just made and tap it until it makes a small notch, just deep enough to keep your drill bit from sliding off the mark.

4. Drill a 7/16" hole in the pipe. You want the hole a little smaller than the hole you are tapping so that you get some good threads.

5. Take your 1/8" NPT tap and tap the hole. When tapping the hole you should only run your tap in about half way (about an inch). That way your barb fitting doesn’t bottom out.

6. Take a file and file off the rough edges around the hold you just tapped. Once they are smoothed out it would be a good idea to run the tap in again to clean up the edges. The same distance about an inch.

7. Now take a rag or a shop towel and wipe around and inside the tapped hole. Just make sure the metal shavings are gone. (It would probably be a good idea to clean out the turbo outlet pipe, to make sure all shavings are gone)

8. Ok, now take you Red loctite and coat the bottom half of the threads of the Barb fitting. (Make sure to only do the bottom half of the threads because when you thread in the barb fitting there will be a lot of extra loctite)

9. Thread in the fitting into the hole that you tapped inn the turbo outlet pipe. Once hand tight then take a wrench and turn it about 1/2 a turn more. Just until it is snug, the loctite will hold it in. DO NOT OVER TIGHTEN THE FITTING OR YOU COULD STRIP OUT THE THREADS YOU JUST TAPPED, AND THAT WOULD BE BAD!!

10. Wipe off the extra loctite on top of the pipe.

11. Now take it inside your house or keep it somewhere warm for 24 hours. I put mine on one of my vents in my house. Just keep it at around 70 degrees or more.

12. When 24 hours is up. Install the turbo outlet pipe back on your car. Do a boost leak test (which you should be familiar with). Once there is no leaks go have fun boosting at any psi you want to again.
