I have been tuning a 99 dodge durango jtec 410 stroker and have the following issues. I have spent countless hours dialing in the fuel maps and have the vehicle running nearly perfect. I then set it to closed loop and the stft's are driving it lean, refer to datalog. The O2 sensor is showing lean but the stft is taking fuel out????? I have attached tune also. I am very confused and appreciate anyone's insight. vehicle will idles rough and stalls at coast down in closed loop. Thanks in advance for any help
