well I've been lately on a racing site in P.R. and there's this guy claiming his 02 XD top out at 131 MPH on an auto but chek out his MOD 17 or 18 " wheels,ingectors and ecu. I've been talking to this guy for few days now but to tell you the this guy makes no sence. every time I say something he comes out with something more senceless. HOW THE HELL THIS 3 MOD WILL MAKE YOU TOP OUT AT 131 MPH. the only way I know is changing the ECU and that alone won't do it.
