HPF stage 2 meth problem

On race/meth mode, I think Everything is working fine but hard to tell.... I might feel some fluttering on the very top RPM range! Also if the car is cold like it sat overnight, I can get 3 to 5 pulls with the meth before car starts acting up... Once the car is completely warmed up I seem to have the problem with the pump/meth setting, Any ideas
Sounds like knock and the Aem is pulling timing to compensate... Do u have ur Aem unlocked ? Best way to know is pull the logs... If u need it unlocked ask John Reed for help. johnreedracing@gmail.com ... U dont want to mess with this if meth is not working properly u could do some damage
