I ran a hell kitty with my 03 cobra I ran him 3 times and never saw him then we switched cars and he ended up beating me with my car,I was pretty excited when he wanted me to drive his car and the screen in the center said it was on the 707 horse power setting his was bone stock for sure and my cobra put down 642 horse to the wheels.now dnt get me wrong for a factory car it hauls but it feels like the srt cars they feel heavy,and after driving the hell cat I couldn't wait to drive my car I actually have an appt. to rave my car retuned because the tune is almost 6 years old granted nothing has been changed since then but I wanna go to a hand held tuner rather than the chip it has in it,plus I am going to upgrade the fuel pumps if anyone has suggestions on what to go with I'm all ears it has a kb boost a pump on it now with stock pumps.
