Any one know if the local Chevy dealers will reprogram my ECU for better performance of MPG's? have looked into getting a programmer for my '06 LS and can't justify the cost of one just for a possible one time reprogramming. Or do Ya'll have any other idesa to get this done? Would it be better to get a pre-programmed 'chip' or something of that nature? Appreciate this forum 'cause I have learned quite a bit bit about my 'balt from reading the different forums. Noticed after dropping in a new K&N filter the car was more responsive and appereaed to have more torque. Now like the rest of us speed freaks, I would like a bit more umph!
