I also would try another fuel filter, since you have been running vegie,, maybe waxed up? Also, does it run absolutely TERRIBLE when down on power? Rattles, knocks, ect...? Like it's starving for fuel? Or just has no power? (But not terribly noisy from under the hood?)

P0232 Fuel Pump Relay Driver Failed Off -----> This is NOT a common code, you may have a fuel pump relay going bad, and causing you intermittent fuel pump problems, which your symptoms DO sound like to me.
P1247 Turbo Boost Pressure Low ----> Boost leaks?
P1211 ICP Not Controllable - Pressure Abow/Below Desired ------> Common with a chip,,, probably nothing.
