hi all,
I recently had a PFC installed and retuned on my 32 GTR. Was previously running an eManage making 285rwkw and was getting around 420km per tank city driving.
With the PFC install the tuner leaned the tune out a little and got 311rwkw but now im seeing 320-340km per tank with very similar driving patterns.
Another situation im baffled with is the lag. Im getting full boost by 4600rpm with N1 turbos . Mods include 3.5Inch exhaust from front pipes back (std dumps), std internals, std cams, cam gears, Sard FPR.
Can anyone suggest some reasons why boost is coming on so late and fuel consumption is so crap now.
thanks heaps
