A Boost Cut Controller / Fuel Cut Defender.

 

I was told in a previous post that if i tyred to put a "boost cut controller" on a stock exhaust system it would be all bad, as it would get way to hot because the exhaust gasses could not get out quick enough due to the restriction of the stock exhaust system.

A BCC only stops fuel cut, you can fit it but it is pointless, as said above you will never hit fuel cut with both cats in.

Misfire? possibly needing new plugs.

 

Do you have a boost guage, if not why not? What boost is your guage showing?

 

Unless your stock cats have been gutted you will not hit fuel cut.

What boost are you running? Fuel cut is a nasty thing to experience, when I got it on one of my Supras it was an almighty bang car died for a bit.

 

Do you get any warning lights coming on the dash? i.e. the warning triangle, any error codes?

 

Have you increased the boost in anyway?
