I now just send it to ED when I make a change in the engine and need the pcm worked on. A while back I had been pulling my hair out trying to get faster/ more consistant, it did not matter what I tried in tuning the PCM I could not get there. Sombody suggested letting Ed tune it by mail so I got another pcm and sent it to him. To make a long story short he picked up the car 3/10 over the best I could do with a MAIL ORDER tune up. I have heard there are some limitations on what you can do in the higher RPM tables but I do not know exactly what they are. I also have thought about going aftermarket with a Holley or FAST XFI system but the car is so damn consistant and the driver has finally started to act right that I am afraid to change anything.
