Many claim that the main reason the DFI's blow more often then the older EFI/Carb motors is they are very lean in order to meet the EPA demands and Fuel efficiency. It is common knowedge that lean is mean and run well.
I know performace shops hav been successful in playing with the limiters on the ECU, but has anyone thought to richen the fuel and take them off the ragged edge EPA be dammed.

Thought just popped into my head.............
