Bob.....were the head gasket issues you've encountered a result of pumped engines? On forum B, it seems that those who delete are pushing for higher HP/torque, so I could see where that will cause failures. However, if someone simply deleted emissions and kept it at stock or close to stock HP/torque levels, I can't see where it would put any more pressure on the OE equipment. But I'm not a mechanic, so I could be completely out of line.
When my son bought his '12 Mega Dually, he deleted it and added a tuner on day one. He drives fast and tows heavy with no issues at all, he did tow on the lower settings and was careful at all times. It had the 68 rfe. His '16 Mega Dually has the Aisin and only the BD throttle booster.
