Hey manged to get the FG XR8 airbox to fit on today after some fiddling around (tight fit )
but its on just wondering with the extra air induction now should it be retuned to acomadate
the new intake ? or will the computer adjust its self ? read on another furum people had suggested a retune now then leave it . ??

probly not worth it yet chukin away a couple hundred bucks fore just a small mod.
wait till you have done more mods so you only need to do a tune once.

get everything done then tune. leave exhaust till last if possible as that will set off the o2 sensor anyway requiring a tune. v8 box is good upgrade, really livens up the throttle.
