Most workshops will charge you per labour hour which is normally around the $80 mark.....i had my fuel pump and boost controller fitted for i think $80 and a dyno run to see if it all worked fine and to tune the EBC.....all and all it came up to $80 as it took them roughly 1 hour to do lol...
Call and find what workshops will charge you mate.....
