Hey guys,

Quick question which has probably been answered but couldn't find it on here..

I have a BA MKII 2005 XR6T and my car will not boost past 4000 rpm. it is all fine up until the 4000 mark then it just dies. If I keep my foot down it just stays at the 4000 mark and wont go higher.

Boost still reaches 14psi before cutting out.

Any info would be appreciated.

Stuffed cat would be my guess.

Will it rev in neutral ok?

Cheers man I'll have a look tomorrow.

If it's not the cause any other ideas?

Fuel pump or filter ?

revs in neutral fine, just while driving. all gears too

Did you just buy this car? whats changed or what did you change from when it didnt do it to when it started doing it. It hasnt been set up with a rev limiter or anything silly like that?

Got it about a month and a half ago. It was fine 2 days ago then BAM... this is happening. haven't changed a thing.

I am gonna say coils/plugs or your fuel filter is blocked or the line on your submersible pump has come off or perished, what mods have been done, aftermarket intank fuel pump?

My money is still on the cat.

we have given him some things to look at anyway...if you find something be sure to let us know
