No, at the moment it is just a standard kit as fitted to cars for the last billion years lol, dont even have an oxy feedback sys on it yet, just a manual adjuster, im still waiting for the electronics side of it to show up, they are on back order from italy, but i have a 90L tank behind the cab, and as for power loss, i have a bit more on petrol (i wouldnt have guessed that after fitting a vapor ring that is only about 50 odd mm iin diameter, so maybee its all about airspeed, not airflow) and on gas, almost un noticable in low range revs, but up high after about 3500 when hard accel it feels to be leaning out a lot, but that will all fix up after the feedback sys goes on it, and it seems to run out at about 4600 on pet, so thats the intake restricion coming into play. But at the moment, its all worth it, im getting about 16l/100k on gas, as opposed to about 11l/100k on pet, gas l/100k will improve with closed loop sys, but even now, at about 65c/l for gas, its WAY cheaper
and like my sig suggests, i still know where the pet switch is wen i want the ponies unleashed
(side note, it could still spin the rears in the dry with a tandem trailer with an xf ute on it while i was on gas)
