Default Would A Missing Nut On The Up Pipe To Turbo Cause Issue

So my car was running strong after getting tuned by Keith Fields. It ran good for about a week or two until I started noticing a loss in power and the ECU had learned to pull about 10% fuel. Well, to notice, I look at all my exhaust gaskets and notice that I am missing a nut on my up pipe to turbo.. Out of three, I am missing one. LOL.. Would this cause a problem like causing the car to run crappy and make the ecu pull fuel? Also, I think I have a DP to midpipe leak as well as a dp to turbo leak. I'm replacing all the gaskets in the car over spring break and re-setting the ECU to see how it runs.... So my question is, would the missing nut cause that issue?

Yes I had the same problem when I got tuned my car ran really lean because of the uppipe leak. Fix that leak and def the turbo to dp leak also. As for the dp to midpipe leak I have alittle leak there as well but it will not affect performance at all it will just sound like crap.

anything after the turbo will not affect performance (for the most part, take this with a grain of salt)

on the other hand pre turbo exhaust leak = tune being completely off, exhaust gasses are not pushing the turbo as they should be.

Well the problem is that is is the nut on the backside of the turbo. I'll have to remove the DP to get to where i need to be and I don't have any extra gaskets. I'm ordering some from Josh at import image today. Be taking on this project soon. It'll most likely require a re tune though. UGH! More money. LOL... I'm helping to make Keith's house payment. LOL When it got tuned it ran like a champ for about a week. I guess it needed time for the gasket to blow... This sucks. The

And? Reuse the DP gasket. You don't have to replace an exhaust gasket everytime you take it off.

Well that makes it alot better.... I guess I was dealing with a lot of picky Subaru owners becuase from what everyone told me it is most likely a good idea to go ahead and use a new gasket every time you take one out... LOL.... So in light of this I'm actually going to go ahead and thread that other nut on there right now!

If I am going through the hassle of taking it all apart I am not going to chance it with a $15 gasket.

Yeah... Well I put the other nut back on but I fear it is too late.. LOL..... I'm most likely going to have to replace the up-pipe turbo gasket. LOL. May as well replace the DP to turbo as well as DP to midpipe gasket too!

You are missint one of the nuts that secures your turbo to the up-pipe and haven't had a problem yet? Hmmmmmmmmm..... Interesting. LOL... Well it has definately caused me issues.... The gasket is pretty much gone. LOL... That particular area is probably the area of the exahust with the most pressure so it's hard to believe you haven't had a problem yet.

If it's the OP's case where it's freshly put on there would be no problem reusing it. But it's been on for 3 years then it might be worth it. It really depends on the condition of the gasket when things are pulled off.
