If those odd programmable outputs have appeared on their own, I'd run an eeprom-clear before reloading the tune.
Re piston holes: I mean mechanical failures happen when they happen, and with a new built engine I'd be thinking about that too.
If eeprom-clear and reloading the tune dont fix it, I'd compression test all 4.

okay, can u explain how i would do that?

Eeprom-clear? Its a "firmware" you can download and install with speedyloader. It zeros out all the eeprom.
It runs when the mega boots, so after you've loaded it and rebooted the mega, reload the firmware and your tune.

Okay thank you very much. I hope this will fix it

Sanity check if the eeprom-clear doesn't fix it, how old are your spark plugs?
