Ritek R03 strategy Swaps on the 1653S

hey guys, Im just wondering if there is any way I can get better results out of my Memorex 8x DVD+R Media. The media code is Ritek R03, I have reset the learnt media EEPROM on the drive, which had marginal improvements. If anyone has done strategy swaps, please let me know. My firmware is CSOK LEDfix. the drive has been crossflashed from a 1633S. An image regarding PI/PIF scans is attatched.
