I don't know of anyone else that modifies ECM's. I did lots of research on larger high impedance injectors and other alternatives. The easiest thing to do is just buy an already modified ECM. You see them in the parts for sale forum all the time. I found one in less than 2 weeks after I started looking. The more expensive alternative is to go to the FAST setup and be done with it. Most people that are selling a modified ECM are switching to the FAST or some other aftermarket ECU. Good luck.
