you can touch the dyno 4 under 250... then every time you go back its at least another 200 bucks at least... (when you make more changes) i am not saying that a dyno tune isent the best way 2 tune a car but 4 the small amount of work that he is getting done it just isent worth it...,now if he was doing a cam hedders top swap or a turbo then yea i wouldent think twice and any way you look at it a caned tune is the worst way of a tune because if you know any thing about tuneing... you will know every car is different and they dunt make it work perfict for your enviroment sry about the spelling lol...
