I just got done installing the Sai Li fuel system. Set the base pressure to 55 psi and kept the vacuum reference port open to atmosphere per tuner commendation. They sent me the base tune which is limited to 5K rpm and I did my idle, Rev (1500, 2500, 3500) and Slow RPM climb logs. It showing 60% lean. AFR1 is showing anywhere from 1 - 1.4 lambda. The gauge is showing AFR1 at 18 - 19 and AFR2 at 15-15.8. Tuner asked me to check for any loose pipes. Cant find any loose pipes or fuel leaks. Any pointers? Any help is appreciated.
