I have only encountered 29e0 and 29e1 when using e85 mixes and non flashed DME aka jb4 g4. Under COBB's ots e30 maps, I have not thrown those codes whatsoever. Oh, and I've been running e85 mixes for more than a year by now and still using stock lpfp and hpfp. I have had to replace my low pressure fuel sensor, but I'm not sure if it had any correlation to e85 mixes as I may have had that code when I first got the car...
