Hypertech Max Energy E-Con?

[gsvar2004]

this is my first post so i will introduce myself. I have a 2004 Silverado 4.3l V6 with magnaflow exhaust, k&n Intake system. I dont get very good mpg around 17 for both highway and city it seems no matter how i dirve. I am lookin to improve MPG, and up the horses a little bit. I am not looking to turn my v6 to a beast cuz i know that just wont happen. I am wondering does anyone have experience with the E-con or know anyone who does? I would like to see others opinions on this programmer before i drop 330 on it. Any advice would be appreciated.

Thanks.

i have 4.3 silverado and one thing you could do is cut the diffuser off of the throttle blad, search for it on s-10crewcab.com , there is a full right up on it, i did it and it improved my highway mpg and will help out in the city a little bit, also better acceleration
