What would be the issues with JET? If you're using the chrysler ECM you wouldn't need to worry about quality issues, would you? What type of programing did they do? Custom or one size fits all? I had a friend when we use to race 2.2 turbo's that could make modifications to the fuel and timing curves with his laptop, and that was over 10 years ago, how come you can't do that now? My main concern is the transmission; I race it and even at WOT the shifts are long and spongy. I want to change the duty cycle time to almost nothing so it won't burn it up.
