DavidF Member 31 Member For: 5y 5d Posted 06/12/19 12:24 PM Share Posted 06/12/19 12:24 PM I am new to the forum and have just purchased a 2007 AWD turbo territory with 100k km on the clock. I have noticed that mostly under full throttle and when the gear changes form 1st to 2nd the car cuts and feels like it has run out of fuel. I have also noticed this has happened at 4000 RPM as well. The car runs and feels very good except for what is mentioned above. I have serviced the car hoping it was a blocked fuel filter. I am not sure what exactly has been done to the car and will list what I know below. 3 inch Exhaust Air intake box ECU tune Was told that it got 280kw on the dyno. Any suggestions as to what steps I should take to fix this problem? Link to comment Share on other sites More sharing options...

Get it up on a dyno and check those AFR's , duty cycles, pressures etc. You might have got a bargain, but for a couple hundred more you'll either know you got a great bargain, or managed to avoid a big fix by spending small money on a small fix. I hope you got a great bargain! Link to comment Share on other sites More sharing options...
DavidF Member 31 Member For: 5y 5d Posted 07/12/19 10:22 AM Author Share Posted 07/12/19 10:22 AM (edited) The car has been taken back to the tuner and he said that the ECU is set to protect the car from damage and that's the causing the car to cut out. How would I bypass the boost control solenoid? Edited 07/12/19 10:25 AM by DavidF Link to comment Share on other sites More sharing options...

DavidF Member 31 Member For: 5y 5d Posted 07/12/19 10:30 AM Author Share Posted 07/12/19 10:30 AM Thanks, I will give that a try tomorrow. I worked a fair bit on Fords 25 years ago so this is a very different experience working on the Territory Link to comment Share on other sites More sharing options...
DavidF Member 31 Member For: 5y 5d Posted 21/12/19 10:07 PM Author Share Posted 21/12/19 10:07 PM I bypassed the boost control solenoid and under light acceleration the car lost power and splattered. I rang up who I was led to believe to be the tuner and spoke to him about the cars performance. He said he was just the person doing the RWC and dose not have a dyno!!
