Fuel cut

[Iwan-g-g]

I'm just after a bit of advice, I was driving on the flyover doing about 60 in 4th gear overtaking and the boost gauge showed around 0.9 bar and it hit fuel cut and one hell of a judder.

The only mods On my glanza is a Arc top mount intercooler, decat, 3" exhaust. Standard actuator.

Any ideas what it could be?

Thanks in advance

Boost creep causing fuel cut. If you're still on the standard wastegate its gonna keep happening i'm afraid.

So if I put a hks adjustable actuator on do you think it'll stop boost creep?

Bump on this thread!! I recently bought a gt and if im crusing along its fine but when i put my foot down it jolts and splutters, does this sound like fuel cut to everyone else

Mods are arc top mount and a hks system from cat back

Thanks in advance

Have you got an aftermarket ECU as if not that will be one of the reasons you will get fuel cut, also the standard CT9 will boost creep quite a bit anyway, You could always port your CT9 wastegate to help the issue a bit but it will still creep at this time of year due to the cold air.

Exactly the issue I had before I changed to the CT12

Porting of the CT9 wastegate can help but probably wont completely stop the fuel cut

Best bet is to weld the wastegate closed and fir an external wastegate (Tial or equivalent) and fit emanage blue or similar
