Ceathreamhnan is spot on, no point reving the tits off it, itll do nothing for you.
which engine does that one have ?
mined the 6 cilinder, but i;m thinking yours must be the 4 silinder ?
for me, mine pulls well at 1500rpm, then pulls good and hard from 2000rpm, and i change up at about 3500rpm...
mined a bit strange because theres so much tork there, at first youll think the car isnt very "nippy".... then you realise that your driving along at 1000rpm and just think the car is slow because its still pulls well, just not really well
