Recommended Posts

I have a UK spec which ive decatted and fitted a boost controller gredy profec 2 I think now when i floor it it pulls like a train untill top gear then it cuts out for a split second i get the red triangle and the ecu light come on for a couple of seconds then it cuts out a second time same as the first then it pulls through I thought this was because I have not yet fitted the THOR FCD , after reading this is there another problem and I dont need the FCD ive got new plugs new coil pack clips, now im confused !!

Sounds like you're hitting fuel cut which kinda confirms what I've been thinking. I reckon the UK spec is ok up to 1.1 bar of boost, but when you exceed that, it'll hit the fuel cut.

I'm surprised there isn't a hard n fast conclusion on this to hand, tbh.

 

It needs one mate if you go over 1bar with a BC. I've rear it a while ago. It's only if you just remove the cats then its fine. Plus no harm in installing one anyways just make sure it's on the correct setting.
