I am considering buying the Hypertech Max Energy E-Con Programmer for my 08 Silverado with AFM. I already have the K&N and the flowmaster 40 exhaust and I am averaging about 18.6 mpg (city/hwy mixed). I was wondering if anyone has used one and if it was worth the $330. I am looking for fuel mileage not really the HP. I drive 35 miles to work one way so a couple MPG's would help. Thanks

i have the max energy which has the smae programming as the Econ. mpg wise i got maybe a .5 mpg increased. power wise it helped a little but not much.
