It really isnt that much louder except when you mash it! Like I said, I think it is a good sound. But for a passenger vehicle with small children we want to keep this vehicle as quiet as possible. If I were to put one on again it would be this one!

I remembered where I saw the pictures! I really like the look, and it is a GM product, and no oil!

btw, the 91 octane settings defenitely requires 91+ ..i drove to the gas station with 87, and it had noticable knocking. i personally love the way the truck shifts using the superchips provided shift settings.

also, if you have it plugged in while driving, you can do 0-xx mph tests. ill have to post some 0-60 tests with the superchips programming and without..and see if its worth a damn. next time i swap my 17s back on, ill do it. probably not worth doing with 24s.

 

I gota superchipfrom the dealership already installed and programmed.

Where do you plug it in the car?

I might have to take a look and see what they programmed for me there. I like very much the idea of using the tow mode to store the performance settings and be able to go to performance mode with a push of a button....

 

Underneath the dash, right under the steering column.

 

Thanks. I just connected and the performance profile was plugged in.

Now I know I need higher grade fuel... [&:]
