i had a auto VZ Ss ute with extractors, exhaust, k&n filter and tuned. Was 333rwhp (from memory?) Wasnt loud and you it looked very orig under the hood.

They put the tune through the power mode button, or some crap like that. You could tramp it with no brake and the thing just lit up. Would shift into second and try and turn itself around 180 degrees! heaps of fun when you wanted it but still very tame as a daily. One of the better cars ive had i think
