Sony DW-Q58A firmware questions



I recently purchase a Dell E1505 came with a sony dw-q58a and immediately upgraded to UYS3 firmware after saving bin file. Results seem to be okay unit working fine, records DVD+R at only 6x on 8x media. When I check the recorder in Nero info tool, it shows as being an 8x read 6x write recorder. When I check the specs it shows as an 8x recorder not really a complaint, but just puzzled. Everything else about the upgrade is fine good copies both dvd and cd’s, just wondering if anybody has any info.
