Going to be taking my 94 Lebaron 3.0 up to a Chrysler specialty shop to see if they are able to flash the stock ECU. They told me they would basically have to see if there are any available copy/paste tunes for it. As of now, it is slightly modified. I'm looking specifically for an all motor 93 octane tune. Have been told that advancing the timing 3 degrees helps alot, and also got a set of Magnecor KV85s and NGK copper racing plugs. Does anyone know of any tunes for the ECU that have a higher compression ratio and air/fuel ratio? Unfortunately I'm not wanting to begin working on internals until late spring. Other modifications as of now include a cold air intake, a 180 degree thermostat, and a straight through Magnaflow muffler.
