Never heard of this and would guess it is an urban legend. You can buy a reflashed, performance ECU from a dealer (MOPAR) or from howell engineering (AF/X), or maybe on Ebay (avoid the JET). MOPAR will give you about 10 more HP, raise the rev limiter to around 7500 RPM, and the top speed limiter to 145 MPH (do not expect to see the 145 without some serious additional mods), and the AF/X a few more ponies than the MOPAR.
