Okay I'm new to this board and was looking for some serious help. I've been having this problem lately with my car where when in 4th and 5th gear when I boost at 20psi the car seems like if it shuts the fuel. Today I was in 3rd and I think I boosted to 21 and then I got hit with a code, P1103 Comes out as Turbo Charger Wastegate Actuator Circuit Fault. Does anyone know the cause of this, and if so do I need a new wastegate? I turned the boost back down to about 18 and it seems fine right now. But my question is, will my shiet blow up soon? =(

You're getting fuel cut. You're running too much boost for your injector size. I don't see any real fuel mods in your sig, so my guess it yeah, if you keep it up, you're gonna break something. Turn the boost down until you do some fuel mods. Also, unless you've got a bigger than stock turbo, you're not going to make any more power at 20+psi than 15-17psi anyway.

Thanks A Bunch, I was figuring it was fuel cut off since it felt the same as if u go 135 and then hit 136mph and boom... no more power. I'm keeping it at lower boost now. Don't feel like a rebuild right now.
