I could be wrong but I don't think the engine has sensors that "read" exhaust or intake gases to meter the EGR so likely a block-off plate would work. Try it and see it would be very easy to remove if it doesn't... I also would like to know how the computer controls the boost. Never heard of an electronic wastegate per se but have seen them controlled by vacuum. The system may use vacuum to hold the wastegate shut and then vent to release boost. Or it may be a springloaded standard wastegate with a vacuum assist to dump boost if commanded by the computer. Disabling should be fairly simple and easily returned to stock if it doesn't work out. Sounds like fun. RT
