I recently fitted a magnex 3inch downpipe and de-cat to my evo 8GSR i also have a blitz nur spec R cat back system. on 2 ocasions it has fuel cutted in first gear, has anyone else had this kind of problem? is it really necessary to fit a fuel cut deffender, if i do fit the fuel cut deffender will the engine be mechanicaly ok to hit the higher boost level? does it take time or something for the car to adjust to the new exhaust system?
