judgee New Member 23 Member For: 14y 2m 4d Posted 01/05/12 02:36 AM Share Posted 01/05/12 02:36 AM Hi guys have a suspicion that my 2005 BA MKII XR6T is overboosting and going into limp mode.The car is stock besides a K&N Filter and Snorkel + a FPV F6 cooler. Has run fine with these mods and nothing has changed but last night it was a little colder than normal up here in the NT and When I gave it some it would build boost and then hit some kind of cut out around 3-4000RPM. Happens every time now. Car did have a 1/4 tank at the time but have since filled it up with BP Ultimate and still does the same thing.Any ideas on what to check?

Seems a bit better today but still breaking down at higher revs. I'd rather see a tuner than go to ford. Anyone know a tuner in Darwin Link to comment Share on other sites More sharing options...

judgee New Member 23 Member For: 14y 2m 4d Posted 01/05/12 09:28 AM Author Share Posted 01/05/12 09:28 AM Yes, Plugs replaced about 500km ago. Standard Ford plugs. Car only has 90,000km. Been driving it round before and I think it could be more of a spark issue as it boosts fine and once it hits around 3500RPM it backs off like something is holding it back. Pulls hard up until then though and if I load it up in a higher gear like 4th of 5th it runs perfect. it just seems to do it in 2nd and 3rd when it gets around 3500. Called Peckys Performance but cant get in for around a week or two. Link to comment Share on other sites More sharing options...
