Does the car have to stay auto? If so, you might be looking at a ZF swap in future. -
Yeah its tuned relatively conservatively being dynoed at 525hp with every bolt on and top end of the motor built wtih HKS vcam and springs etc. -
Probably. But keep in mind that all Joshua was saying that because of things like timing scatter, and many other related and unrelated things, tuning too aggressively should be avoided. Hence why both he and I said that fitting the cat shouldn't cause you to suddenly fall into the danger zone. -
I’m running links ecu and an upgraded crank sensor. So I guess I have less chance of this.

The stock Nissan CAS gets very messy at high rpm, particularly with bigger cams/springs, and most aftermarket ECUs don't do as good a job of filtering the noise as the OEM ECU somehow manages to do. So you get "scatter" in the timing signals that can be really destructive to the ECU's knowledge of engine position. And so you can get spark firing many degrees early, leading to catastrophic detonation events.
