Xr6T Boost Problems - Need Advice.

[Titleist]

Hi Gents, New here and just wanted to see what you guys make of this. I will be booking the car into Tunehouse to get them to have a look at it but want an idea of what might be wrong before I go.

Stock 2011 XR6T.
-Car feels very underpowered, almost like it has no Turbo. I can hear it boosting up hard but it goes no where!!! it just has no kick to it. The weird part is sometimes it wakes up and flies and sometimes it doesnt.

-Fuel useage has gone up a lot average is on 17.8/100 (use to be around (13L-14L/100) - I notice it is using more, I use to get close to 2 weeks out of a $60 tank, now I am getting 1 week at best.

-After a throttle body clean and tightining up all the pipework things got worse.It's like the boost goes no where.

I have checked the pipework for cracks, leaks and found nothing and I am planning on changing all the intercooler and throttlebody piping with aluminium in 2 weeks time.

What could it be?

Cheers...

Boost solinoid maybe?

Have you taken the pipe off front of the turbo and had the car running to see if its spinning freely?

Maybe the waste gate flapper is sticking or actuator might be stuffed?

Jim is one of the best . He will get you sorted.

Get a tune while you are there.

I want to get in there and try the wd40 trick but just dont want to F anything up. My wife needs the car all week. I havent taken off the pipes im not really that confident with doing this, I know ill stuff something up.

does the car have the stock tune or has it been tuned?

Have you done any mods to the car at all, include air box, exhaust etc?

Jim should be able to sort out as anyone online will only be guessing, no matter how good they are, but your issue almost sounds like an overboost, but as I said, guessing

Fit a boost gauge so you at least have some data. Or at least buy a obd plug in adapter that will talk to the torque pro app on your phone. Can log boost on this as well as a bunch of other things. best 15 bucks I have ever spent.

Thanks for that mate, I will definately check it out. Would be nice to see how much boost is actually being forced in...
