A lot of lancer MAF's have a high incidence of infant mortality, but they go straight to limp mode and the warning light never turns off. it has a real high idle when the car warms up as well.

He might be talking about your proprietary XML's that effectively lock people out of their ECU's. Hopefully you're not using those anymore though.

You cannot lock Evo X ECU's so none of what is being discussed has any merit.

What's the weather been like where you are in the USA? I've had my share of P1235 and P1238s at part throttle in the wintertime. The atmospheric changes take you to the upper limits of your boost/load targets, if it becomes a problem you'll probably want to have your tune touched up and/or disable the DTCs.
