I ran a ZZP PCM as well for 2+ years with no problem. Once you get the Aeroforce gauge in scan for KR and see what youve got. No point in blowing that much more money on something you already have. You could be spending it on other parts. Once you get further into modding you will need to get another tune anyways. Scan, get some more mods, and get yourself a custom tune IMO.
