Hello. I have fitted a z32 MAF and gtr injectors to my rb30. I used the base tune from Matt. When I accelerate it goes fine to a point then my injection duty cycle drops to 0.82 instantly. It dosn't go back up for a while stalling the engine. I dont have my wideband installed yet but its clearly cutting fuel for some reason. Just wondering if anyone has seen this before and what I need to do?
I have attached screen shots of the nistune log. 1 is before it cuts out the second is after its cut out.
Fuel cutting as soon as I hit boost?

Never mind. Had a speed limiter set a 40km/h. goes hard! 
Re: Fuel cutting as soon as I hit boost?
that's funny, its normally set to 480km/r or some ridiculous figure.
