Anyone have this installed I got a guy tht will do it $325.00 installed brand new, let me know pleaseee

 

i have the flashpaq and i enjoy it there is a noticeable difference in the car especially with the line pressure and the shift points raised

 

I had the Cortex on my ISS. It ran hard with it. A dyno tune would be better - but the Superchips worked as advertised for me.\

And install it yourself or have him show you. If you buy it, learn to use it. It's pretty easy.

 

I have it on mine and it is as advertised. Made a night and day difference between stock v. tuned. I believe I am going to get a custom tune on mine soon when I get my headers.... I will have to see if the cortex pulled enough fuel for the headers since they throw the maps off.
