On my GT, when I take the keys out of the ignition barrel and open my door with my window still open, It allows me to close them without the keys in, is this an optional extra?
dont get me started on the ringlands on these, I personally wouldnt go above a bar boost on my GT... quite content atm on .6 lol.. no fcd = me killing actuator like a noob and smashing fuel cut doing my ringlands in get it forged mate!!!
throttle position sensor? my old n/a was stuck on 3k revs until we readjusted it (was on a 4efte tb) your n/a one might be fubar'd? either that or an earth are most common things
get the timing done, you haven't turned the rotor atall? could have advanced/retarded timing maybe? id get that looked at tbh dude, sounds similar what happened to my green n/a, timing was out was cured when it was set right
