Ok i have never had any of my cars professionally tuned.
I just brought a eb xr motor and wade 977B cam and want to get it tuned properly.
I have heard tunes cost up to $500 plus with a j3 chip and take a couple of hours.
What is involved in the tuning cost, obviously they tune your car so it runs better but what do they do exactly that costs so much?

Labour cost, dyno useage cost, and paying for the knowledge.....it all costs.

and make sure you got a full tank of petrol your gonna need it!
make sure the tyres are good dyno places hate it when you bring in s**t tyres on the car!

Fair enough then
