I've managed to source some t4 nozzles and they being fitted start of next mth,iml probably gonna leave the remap till jan/feb so with a standard engine (afn) plus a digital tuning box what sort of power should I see? I been told the box on max will give 140-145 bhp
,will the nozzles see me between 150/160?
I wanna leave the map till I can afford a better turbo!!
