    so i spent the 435 bucks on a superchips cortex programmer for my 04 Sierra 5.3 and its a noticable difference but not worth the money anyone had any good results or did i just waste my money and should return it within the 30 days

    waste of money

    you want a custom tune, where they actually ride along with you on a laptop and tune your truck.

    blackbear performance, or have a shop tune some where nearby your city.

    you will get way more MPGs, and actually gain power. When i mean power im talkin about gains.

    You wasted your money just like I did the first time. Send it back and give wait4meperformance a call then you will get your moneys worth. Just give the cortex a few days it will feel like your tune quits working.
