IMho a deviation of more than 5 degrees c and you should mod the table or change themrisistor settings.
And for the record the code you pasted i can take no credit for something i found on github if i felt you could use.
Also do not forget to reset min temp and max temp settings to make full use of the new hot end.

I've generated a thermistor table for the Semitec 104GT-2 as shipped with the E3D v6 hotend, this covers the original glass and the new cartridge type.
This table is for use with the 1.0a and any other Davinci models that have a single 1kohm resistor instead of the 4k7 and 10k as found on the 1.0 models. I know some users have removed the 10k and used the standard Repetier tables. You could swap out the 1kohm for a 4k7 and use the generic tables, but cut and paste is much easier.
Can this be added to the firmware as an option for users who have upgraded their hotends/thermistors please?
#define EXT0_TEMPSENSOR_TYPE 7

I pasted in your code, and flashed it but it still didn't work. I changed the thermistor type to five and it seems to be working, Yay!!

I followed the link and did what it said, and after reflashing the firmware still no dice. I'm pretty sure this is a firmware issue though

So changing table to table 8 won't work in this case unless your rework your main board to be able to use common thermistor tables,
This is in FAQ of repetier for Davinci github : https://github.com/luc-github/Repetier- … issues/104
That said the resistors name described in github are for the first generation - may be not for the "a" one - but status is the same
