For a few months my car has occasionally been shutting off like an over boost but not when revving in lower gears just when foot to the floor in top at 3k rpm. This was happening more frequently so I removed the boost enhancer and put the standard air filter box back on. Boost dropped back to standard but the problem still remained. I filmed the aftermarket gauge so as not to miss any over boost and it does not show an over boost when the problem occurs! Do any other problems trigger the "safe mode"? When this happens on the motorway I could cruise and only use gentle acceleration. After a couple of minutes all would return to normal. If this happen on slower roads the engine would only tick over (like the throttle cable had broken) and I would have to switch off to reset back to normal. Today the "Safe mode" seemed to come on when I was on boost in third and the car became permanently sick! Tick over is strange, it runs very rough at 500 rpm for 3 seconds then a burst of 1200 rpm for 1 second then back to 500 rpm for 3 seconds and repeats this. I can get the revs up by gently opening the throttle but too quick and it goes to cut out. It will drive but its difficult to stop and keep the revs up. 2-3k seems smooth but at soon as I approach 3k rpm the car starts to jerk and if I attempt to drive through it then it gets worse. Any Ideas most appreciated. Mike
