I am trying to find out whether there is a company that sells
reprogramming equipment for Chrysler Powertrain Control Modules.   I
want to be able to re-program the vehicles computer to adjust fuel
management and ignition in order to calibrate it for use with a
supercharger.  What I am looking for is something like the product
offered here: http://www.hptuners.com/   but for Chryslers instead of
GM cars. It must work on the new Chrysler 300 touring (with the 3.5
liter V6) and I would like for it to work on the older Chrysler 300M
as well.  What I am NOT looking for is a "piggyback" system that
alters the signal coming from or going to the computer, thereby
fooling it into changing parameters.  I want to re-program the
computer itself.  Some companies such as www.jetchip.com say that they
offer the service, but do not sell the capability to other companies.

I also want to point out that what I am seeking is not an OBD-II scan
tool, which passively reads diagnostic codes out of the engine.  Nor
am I seeking a device which only allows me to re-flash the computer
with stock programs from the manufacturer.  It needs to have basically
all the capabilities of the product shown at hptuners.com   Sorry if
this is unclear, or in the wrong section. It's my first time using
this service.
