Now i just need that re-tune from aam and will be good to go, but I was seeing my vacuum, boost, and not over boosting like it was. So very good day. I want to thank those that help me figer it out. Also just for the record because of the way it was hooked up AAM is compensating me with a AAM intake manifold.

Sorry for ******* up your install, here's a $2k manifold!

Glad you got fixed before your car pooped. That would be no good. A new manifold is a decent compensation I guess. It's not like you didn't pay them big $$ then they took it then messed up doing an install of what they specialize in. But like I said, a decent compensation due to the fact that your car didn't boom (could easily have with overboosting).

Glad to see AAM with an effort to make it right. Hopefully no permanent damage done during the overboosting and a $2k manifold is a pretty sweet freebie for your trouble. MAKE SURE THE MANIFOLD CASTING IS CLEAR AND CLEAN!!!!

I think it is fair, I never wanted to overboost but it looks like the tech hooked it up for a twin instead of a single. Then since i have never hooked up a bov or waste gates i had to learn; which was about 8 hours and a few drinks in lol. I still have to check the vaccum at idle and set the spring. Does anyone have a idea about waste gate springs? I have the seven pound and using the pressure for the BC, should I keep it this way or go to a heavier spring? Still learning....

I suggest keeping the one you have now as long as its working the way you want.

Are you using a boost controller? Then here's what you need to know in selecting a spring:

In the general case, you want to select the lightest spring that still allows your boost controller to hold the target boost all the way to redline.

If you have too light of a spring, the exhaust pressure at high rev/load will be able to push the wastegate flapper open on its own.

Too heavy of a spring, and you won't be able to dial the boost down if you need.

Now, you may want to go a little heavier that "the lightest you can" so that you have room to raise the boost later down the road... There is probably a range of springs that will work now and in the future.. And don't forget, you can always tension the spring down for adjustment.

Couple things. Make sure you have your vacuum lines clear of the manifold and securely so. Second after much suspicion I found that the springs in the Tial wastegates read a bit off consistently. At first I thought it was my boost controller buat after checking around I talked with a major shop in the area and found that they would pressure test the springs before install and the same inconsistent readings were found with the springs. I finally went with the the next step lower than recommended. The boost controller can only regulate boost from that point up and no lower. But above all else make sure the vacuum lines stay clear of anything that might burn a hole in them. I got owned by a 1/4 inch hole in a vacuum line to the passenger wastegate.

I will do that, i'm getting the vacuum gauge to test vacuum and set up the BOV that way. After that I will check he waste gate springs next Thanks for the info that is really helpful.

You guys are confusing BOV springs and wastegate springs. Glad you got it all figured out. Let me know what your vacuum is at idle and I'll get you the correct BOV sent.

Anywhere on the intake manifold. A cheap gauge will do just fine.

2 updates. First the vacuum gauge didn't come today, so I will have to wait till next week to get the reading. Second is i'm hearing the waste gates open but they sound like they are fluttering and not releasing pressure when they should. the boost just keeps going up.... any idea what it its?

Hey guys got the vacuum measurement, it came in at 19.5 Hg, What are guys thought's? I also turned off the BC and found that i'm not even getting the waste gates to do jack. The boost just goes up till i hit redline and shift, maybe they are stuck? Well this weekend I will take them apart and take a look at and see what springs they put in, maybe they went way to strong.

How much boost are you seeing?
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.

Be very careful if you spike you're looking at a new motor. Maybe pull the wastegates to make sure your diaphragms are not pinched. And it may seem like alot of work but having been through what I've been through I'd pull all the vacuum lines and reinstall them.
