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...
