Gday all, just wanting to get some advice & info on dyno tuners. what is the normal cost for a tune ? and what would they normally achieve ? I rang CGR in Narrabeen and they advised $1400.. I said that's quite steep and they said that's from scratch. so they advised they can do per hour @ $220.. I said how many hours will it need? all I want is to get a bit of extra power / boost. If the car already has a tune, will a new tuner need to do it from scratch or can they just go from where the car is currently at ? Cheers, Ian
