Decided to take the 7 on a 750 mile trip. About 100 miles in the psi was only reaching 2-3 and shortly after that there is none to be had. I can hear the turbos spool but when they do the boost gauge reads 0psi. I can't hear any leaks nor do I visually see anything wrong with the piping. The only thing I can think of is the wastegate is stuck open but I'm open to other ideas.

I am also getting really bad ground hesitation all the way up to 3500rpm. The severeness comes and goes but at times it's almost undrivable and you have to burn the hell out of the clutch to get it above 3500rpm. But other times there is none. I have cleaned a few grounds but it hasn't seemed to make a difference.


I love how all this pops up when I'm stuck between a rock and a hard place in the middle of no where. My car is all factory by the way.

its going into the wind litterally , You need to check all your Post turbo intercooler hoses / clamps . I've had this happen before when

1 hose broke ,

2 hose popped off check everything and then tighten the clamps . if you have stock clamps get some worm clamps for now they should hold

Have you checked any of the connections to your turbo solenoids under the UIM? My car would never boost or would only get to 3psi if I was lucky and it was the connections to the turbo solenoids. If you found the answer though let us know!

Dont automatically assume that the hesitation you're feeling is a grounding issue.

Why do you think its grounding? Because you read it from someone on here, who heard it from some other guy, who thought it was bad grounds?

Assumption can make you chase the wrong issues in the wrong places. Don't name the problem until you're 100% sure of whats causing it. You have all these issues happening with the boost. Hesitation is most likely a byproduct of those same issues.

Get the car to idle at the curb. Open the hood. Go to the UIM. Pull off a capped nipple on the side of the upper intake manifold, on the passenger's side (Left Hand drive USA car?).

You will create a vacuum leak by doing this. The idle should jump higher the moment you uncap the small 1/8" vacuum port. If it does NOT jump higher, then this means you already have a large vacuum leak elsewhere in the system. This is where your boost is going.

You'll have to get in there and inspect everything and chase it down manually.

Check the Ypipe to crossover pipe coupler. All of a sudden had no boost once on mine and while the sun is going down its hard to spot the pipe off the coupler since everything is black, Didnt find it until I had it in my garage with a flashlight finding it.
