$450 is actually a very good price. I doubt you'll find anyone reputable to do it for less. Gotta remember you have to pay the guy tuning the car, as well as dyno rental which has to be enough cumulatively if, God forbid, that $100,000 tool breaks, as well as overhead on any software, computers, and electricity used during the process. If you broke it all down, $450 probably doesn't leave you with a whole lot of profit, when you, in return, get something that is priceless, ie; your car running reliably and safely and making good power. /rant/
