You guys are all idiots.... I dominate all 
In all seriousness though, the standback sucks and has very little headroom for tuning, in fact, it too is throwing in more variables creating more issues. I don't know details of the xede, but that unit tuned has dynod the most power to date IIRC. The ecu sees 18psi as a limit, a safety procaution. Just because plenty of flow for fuel is there and plenty of air for a potentially good tune, doesn't mean the ECU will withdrawal that limitation. The MAP must be clamped below 4.2ish volts, end of story. A new tuning method, other than piggyback, is preferred by all.
Peace
