Titleist New Member 7 Member For: 9y 4m 6d Posted 06/08/15 02:31 AM Share Posted 06/08/15 02:31 AM 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...

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.

Dont want to mess around with it, it's just really annoying I want it to be 100% but it's not..Fit a boost gauge so you at least have some data.

Would be nice to see how much boost is actually being forced in... Link to comment Share on other sites More sharing options...
