I have read suggestions in forums here that a "custom" tune will increase the HP in a 2010 GT. I would like to know what a custom tune entails. Are there any possible negative effects, like reliability? Since more power seems to be the name of the game for most, why wouldn't Ford tune them for maximum power?
I read in another source where the author said a S197 Mustang was tuned at every 500 RPM's up to redline to get the most HP. I don't understand how that one would work.
