..but i just put my rear slicks on today, and theyre 27x10.5x16 so i adjusted for it in HPTuners, I put the new tire height to 27" and now even tho its aware there is a taller tire out back, my BRAKE and ABS disable light are on.

Is it because I have the wrong tire height entered in, or does it not matter and it will show that no matter if its right or not, just cause the ABS cannot function properly with two different heights of tire.

the 27" tire will actually measure out to about 26.5 ...I dont think a 1/2" will throw the PCM off...you can adjust the numbers to see if it fixes it and check the connection by the fuel filter to make sure it's not loose

All you are doing is correcting your speedometer. ABS is not a function of the PCM, The individual wheel sensors are still seeing different wheel speeds between the front and back.
