You would need to put your factory PCM back in for ION to do anything for you. Unless the new PCM was created with HP Tuners...then it would be ok but if it was created with the DHP program...it locks it down. I found that out when my car was on the dyno.
I would put the old one back in and see how the car reacts. I may have missed it....but where did you get the PCM from?
