Well I figured out why I was overboosting. I am retarded and had the wrong vac lines plugged into the wastegate. They were negating each other....

There is a pic of what I did right there. Well anyway I bought a new wastegate because thats what I thought the prob was. I got the car working fine except for the fact that it leaks a little under my deltagate. I tried doubling the gaskets, but that didn't fix it either. So since I was only hitting 8 psi on my boost setting I decided to switch to manual mode with my EVC and up the boost a lil to equalize the exhaust leak. I had it set to 12-13ish and all of a sudden I started having probs.

The PROBS...

I switched it back to my 10psi setting on the low button but everytime I floor the car it gets to about 5-6 rpms and the car starts jerking violently and the rpms start sticking. It like its having a massive boost spike or something. I really don't know why it would cause the rpms to stick though. Any ideas?
