it also depends how your limiter is set. you can either have your fuel cut first or spark. if you cut fuel before spark you will go lean and see KR if you are cutting spark first then the Kr would be from the vibration instead. you should not hit your rev limiter during a shift either. either you are shifting too high or your limiter is set too low. always give your self about 250-300 rpm after the commanded shift as rpm's do climb until the shift is complete. so if you are shifting at 6,000 your limiter should be set at 6300.
also 103 is way to early to up-shift. you say your top swapped, so im assuming you have 3.29's. that would mean you were on the 3-4 shift.... you should never shift 3-4 at WOT. sounds like you need to remap your shift points up top.
