yeh just took some then in comparsion to safc2
sorry for whoring your thread PAV34.
ive driven stock r34 gtt and id say getting a powerfc wont make power delivery any smoother. Trust me they are damn smooth already! (try driving r32 with rb20det haha)
The main difference with powerfc to afc neo is that pfc can adjust ignition timing as well adjusting airflow for fuel while afc neo can only do fuel. While running stock boost, adjusting ignition is not needed. But adjusting airflow would help (a bit more power = a bit more smoother?) as u have an airfilter and full turbo back exhaust which would usually cause it run a tad rich..
400km a tank is decent.. u should look into replacing the o2 sensor of the car if you havnt already. Should be replacing them every 40,000km apparently in the skyline manual.
good luck
