Hello everyone, newbie here, im a GT4 owner

but used to have an N/A sw20, hope you dont mind me being here??? If so i'll get my coat!!

Just saw a standard 3sgte ECU on E-bay claiming to be chipped.

Now as far as im aware its not possible to chip or even map one.

Is this a case of false advertising or am i comlpetely stupid and misinformed???

Also im thinking of a Greddy E-manage to try and improve my afr, anyone got one

? and wat you guys think of em?
Thanks
