Most shops charge $150-160 to tune. Most people a boosted car takes 3 hours for power pulls, driveability etc. $150x3=$450, you're getting off easy.
$200 for a full dyno tune? Are you kidding me? If you want it to be cheap go buy a $30000 dyno and do it yourself.
Tuners have THEIR hourly rate then they have to pay the owner of the dyno.
You might find someone to do a halfass street tune for $200
tell your friend to pay for someone that knows what they are doing like Scotty whose tuned over 1000 hondas it costs money. This isn't a negotiation. You pay for a service.
