    Default Superchips Cortex?

    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.

    Cool Superchips Cortex

    Send it back. I have a Diablo Preditor which you can use there tune and customize it to your liking or find a local shop to custom tune. Try going on the Diablo website for there closet tuning dealer to you. There newrer programmer holds up to five custom tunes. Shop there dealers for the best price.
