Default Installed new pulley, slight kr

well i finally decided to install a 3.5 pulley on my car. the car is entirely stock besides the pulley. the only time i see KR is at WOT. i see 1 degree at higher rpm just before the 1-2 shift, and then 1 degree halfway to 2-3 shift and 2 degrees till the shift into 3rd the timing advance is around 16 degrees at WOT right before shifts.. just wondering, do you guys think that a fwi and high flow cat would take care of my kr?

no way to know for sure, but your chance are very good if you do so.

besides fwi and high flow cat, what would be the next mod to think about on the cheaper side?

what kind of difference would that make without any other mods?
