knock issue

[Rick184u]

so i just got my predator and the C&L Air intake and love it for my 2008 srt8 6.1 challenger. however im getting some knock between 1-2nd and 3 gear while shifting or stomping the gas . i did some data logging and the st knock goes up to 5.50 and the LT gose up to 3.50 which im told is high. should i add fue to rich or lean or decrease timing? im running the 91 cai tune but running 93 gas what should i do. the gas i use is Bp amaco
