C5 Flex Fuel Help with os 12216125

[Neukom720]

Hey guys kept my factory C5 p01 896 PCM as a working backup and installed a p01 0411 with flex fuel os 12216125 from a 5.3L sierra with flex fuel active from factory. I then manually moved all my OEM C5 parameters over to the new flex fuel OS. Used program to change 2002 12216125 os to my 99 C5 VIN, Removed VATS and it starts but runs terrible, throttle barley responds, abs message, traction message, and charging messages coming up on the DIC but checked with multimeter and is charging maybe even slightly to high of charging. My question is, in the system options I removed everything under the gmt800 and turned on all my options under platform Y which is the Corvette, was I suppose to leave GMT800 selected and just select all my Corvette options in the GMT800 row? My factory file i believe said GMT530 so I selected that and did everything under the "Y" platform options. Any help would be awesome thanks guys
