Just installed a Gen. 2 K&N intake and a Jet Chip. So far i've noticed a decent inprovement!!!! Shifting is more responsive.......Acceleration is definatly better all the way thru the gears.
Usually after 70mph the 4.7 is a dog.....but now it actually gets on it!!!!
I know i've read that the cpu will eventually reset everything....but i'm hoping it stays[8D][8D][8D]....if it doesn't....then maybe i'll try the superchips programmer when it comes out.

Also installed the Power Slot rotors all the way around....with Hawk pads on the front and some Extreme Pads in the back. Also Bilstein shocks all the way around. Braking is definatly better and so is the drive.

Now i need to find some headers
