I just wanted to quote something posted on my Mustang website by a tuner.

Ouote: " Mail order tunes are junk Other for a bone stock car......... even then they arent great "

This is pretty much aimed at me since I bought a Brenspeed tune over paying them $300-$700 for a custom tune. What do you guys think about mail order tunes? I know I couldn't be happier with my tune from Brenspeed.

 

+1 I am more than happy with my brenspeed tune, that being said a custom dyno tune will get the most out of your car provided the tuner knows what he's doing.
