    Raylar sells Mahle forged pistons, Cometic headgaskets, and etc for the 8.1L.
    That said, make sure that there was not an issue with fuel system or FI system that caused this.
    Also, I know Procharger (ATI) uses FMU's instead of ECU programming / injector upgrades/addt'l injectors / what have you ... that is preferrable. Talk to Ray at Raylar to get his input on your set-up.
    It would be a bummer to put the good parts in and still eat something.

    Are you replacing all the pistons or just the one you lost? Depending on what all is being done, you may be able to get by weighing one of the old pistons, and seeing who makes one that weighs the same, with the same dimensions and compression and not have to rebalance. Thats the cheap way. If you are doing a rebuild with new parts, then a rebalance would advisable anyway.

    Hyper pistons and blowers simply are not a good combo. Call raylar and save the headaches and hassles,buy some forged, and be done with it.
