jus got my car (r31 gt passage) back from having a manual trans installed. it doesnt run very well, ie. not revving cleanly, makes a knocking sound when revved cold, this disappears when it warms up...
anyway, wheres a good, cheap dyno tuning place in bris, where i can take the car?
the car has a red top nics rb20det, r32 turbo (t28?) and zorst...
thanx in advance
