Wow, those aren't great results!
I wonder if your DW1655 is using Solidburn to learn the media?
Have you installed the BenQ Qsuite? If not, you might find it available here:

On my own DW1655, when I checked the "solidburn" tab, I noticed that my burner had picked up on two sorts of media:
Since both of these MID's should already be recognised by the firmware, I speculate that it has to do with my using some dodgy Maxell 16x DVD+R with mid CMC MAG M01, and some awful Dynex 16x DVD+R mid MCC 004 which were made in China. I might be able to confirm or disprove this theory by putting in my DW1650, which I have yet to use to burn to those discs.
You might therefore try doing a few more burns and checking the write quality again, since it's possible that it will improve.
From all of my own CD-DVD Speed and KProbe tests, however, I find that there is a difference in write quality according to the content! This adds a further layer of murkiness to scan results, which we already know to be fairly approximate. If you want evidence of the latter, just try running the same scan several times on the exact same disc - there's quite a significant amount of variation.
I too was anxious to get hold of a genuine BenQ burner, since by all accounts they are great all rounders. I've somehow managed to acquire a total of seven burners in that quest, and it seems that they all have their own strengths and weaknesses.
Of the eleven different types of discs I've burned to thus far, I would say that my Pioneer DVD-111D gives the best write quality for six of them. My BenQ's are easily the best for DVD ripping, however, and give the best write quality results for three different discs.
Whilst the BenQ WOPC undoubtedly improves burn quality, it does slow the burn down significantly. My LG GSA-H22N definitely gives the fastest burns, helped by it's exceptionally quick writing of lead in and lead out. It seems a bit touchy with media types, however, giving a typical big rise in the tail of a lot of scans, and of my eleven different discs, it is only the best burner for one disc.
I think that you should look out for the right media for your DW1655, based on what gives good scans in other peoples' tests. I wouldn't worry too much about getting down to under 100 PI failures or whatever, since who knows how many discs people burn or how many times they scan them in order to get such amazing scans.
You might also try burning an ISO image file with the latest CD-DVD Speed too, since your scan will then show the burn speed, and the burner used. When WOPC is working, you'll see the burn speed constantly varying as in this scan of a write to a TDK 16x DVD+R disc:
Although the quality score ends up as 0, it was 96 all the way up to the end, and it gets 93 - 96 when scanned in my other drives.
To sum up, I think you'll end up being pretty happy with your DW1655.
