lambda09a New Member 14 Member For: 12y 7m 23d Posted 09/12/12 01:25 AM Share Posted 09/12/12 01:25 AM Hi,I have a 2004 XR6T Falcon and it goes great except one issue I have noticed. When I am boosting around town (ie: up to 80kph in first and second gear) the car seems to boost smoothly and really throws me back into the seat. However when I'm on the open road and boost in third gear to get up to 100 - 140 I will often get a sudden power cut-out. The way to describe it would be similar to the Traction Control kicking in and limiting the engine. However I have been trying this with traction control disabled and it still does it. I am now thinking it may be something to do with a lack of fuel during these high demand longer boosts. Any suggestions on where to look or personal experience?Cheers Link to comment https://www.fordxr6turbo.com/forum/topic/83139-boost-cut/ Share on other sites More sharing options...

Try plugs and coils, but budget for valve spring. Link to comment https://www.fordxr6turbo.com/forum/topic/83139-boost-cut/#findComment-1335203 Share on other sites More sharing options...

I'm hoping it's not the valve springs though as that sounds expensive.

Posted 12/12/12 08:10 PM Share Posted 12/12/12 08:10 PM What boost do you see in the higher gears.More load from higher gear will create more boost, possibly hitting boost cut.

lambda09a New Member 14 Member For: 12y 7m 23d Posted 21/12/12 08:10 AM Author Share Posted 21/12/12 08:10 AM I'm not sure what boost I'm getting as I dont have a boost gauge, but it seems to feel the same as when boosting in second. I dont think I could justify spending 6k to get the issue sorted at this stage Cheers Link to comment https://www.fordxr6turbo.com/forum/topic/83139-boost-cut/#findComment-1339758 Share on other sites More sharing options...
