Higher voltage not achieved with LTC 3757

Can we get +/-70 V in the dual voltage output circuit using LTC 3757 below (Page 32 in the link). When we tried the circuit, we could not achieve more than +/-17 V by increasing the resistance R2=6.2K. The increase of R2 resistance increases the voltage only till +/-17V and after that the voltage decreases. Can someone let me know if one can get as high as 70V.
