nope.dont need to re-tune.

porting will give smoother flow..not really an increase in flow..just smoother flow. so dont need to worry about ur pistons.

porting will increase air-flow while polish smoothens the air flow......its advisable to retune after such mods.....

erm.. i think u guys abit messed up here.

he is asking porting. wat got it to do with smoothnes? if u port but didnt polish it, how come it will be smooth?

porting meaning u r enlarging the stock size. hence its increase flow. with increase flow surely u may wan to increase abit on fuel to match.

EFI meaning electronic fuel injection. what got it to do with self tuning?

Tuning itself means that the ECU learns that there is a change in the air intake system and learn to compensate the fuel itself

there is a limit on how much it can be compensate and the margin is very small
