I am having a problem with overboost on a legacy 94 single turbo car. It has a GGR induction kit and turbo back 3" exhaust - no cat. If you WOT from less than 3k it will overboost and fuel cut by 4k RPM. This weekend i will install a GBE MK2a MBC to give me some manual control over the max boost. A boost gauge and AFR are also being done at the same time.

I am looking at the turbosmart fuel cut device and have seen comments made by people on the board using them - what are your thoughts on this? does it still allow the ECU to fuel correctly at high boost/RPM? is it a relatively safe way of controlling the factory fuel cut?

And finally where can i get one in the UK ?

 

Anyone know of anywhere i can source a mechanical fuel cut device?
