Ok, so I've had my r/t now for about 2.5 yrs. when I bought the car, it already had a short ram k&n intake and flowmasters exhaust. I'm finally at a point now where I can spend a little cash to boost performance. so I have a few questions if anybody here wld be able to answer for me. one of the first things I want to do is a diablo intune. is there a way to tell if my car has already been tuned by the previous owner bc of the intake and exhaust that was added? I've been told by some techs that if it hadn't been tuned, the car wld throw out a code. just not sure...the car hauls a$$ but sometimes I get a slow throttle reponse from the jump or especially when I go from reverse to D. Either way I know I've got to do some type of tuning bc I put 275's on the rears and 255's on the front and my speedometer registers 3-4mph slower than it really is. also, anybody have any good ideas for some nice relatively inexpensive mods? thx guys!
