A friend and I installed the FP/Roush 670hp kit. Yesterday, I uploaded the new calibration supplied in the kit with the pro cal 3. The tune was uploaded successfully however when I started the car (2015 Mustang Gt) the a/f ratio was at 20 and the vehicle was sputtering. It settled into a rough idle but the AF ratio remind the same. The pro cal diagnostic indicated a P0122 and P0223 along with a crank re learn error. I double checked all the connections and they seemed fine. I’m reaching out to you all for some guidance on getting through this issue. Thank you
