Please help with various fuel compensations

I started this thread in hopes of helping others with the same problem. With that being said I am a very novice tuner but I enjoy tuning with such great software. -- We tuned one of our shop cars last night and had 14.2-15 AFR idle/partial throttle, 13.3-13.8 AFR medium load, and 11.4-11.8 AFR WOT under boost When my business partner that owns that shop car was driving it during the day he said he was seeing low 9 AFRs @ WOT under boost I'm pretty sure this has something to do with ECT and IAT fuel compensation, I'm just not real sure were to start. We retuned it tonight and he is going to data log during the day in hopes of helping us figure out whats going on. Any tips on the ECT and IAT comps? Am I on the right track? I'm guessing it was around 60 degrees at night and around 75 during the day if that helps. Also he is running a air to water intercooler on a 57trim vatara d16 setup Thanks for your time DK edit: I'm not real sure I understand the values that you set in the ECT and IAT comps and how much effect they have
