The VEC2 seems too complicated at any price. I've had custom tuning done before -- not great results.
1) the dyno does not represent street conditions
2) If I make more mods, the tune becomes worthless
3) I don't want to fiddle with it
I want to plug something in that is better than stock -- take it out when I may have service work done -- and otherwise be done with it
the Dastek seems like it too requires a custom tune since they don't offer plug'n play for an SRT Viper
