(PM) STAC compression card

I am using several PM3s as a dial-up pool for all of our analog customers.
A total mix of all types of modems. I have channelized T1 DMS-5ESS switch
and currently have 5x10 56k modems with the STAC compression cards in each.
I'm running ComOS 3.8b13 with no complaints. I love Livingston portmasters.

Here is my question. Will I do better using ComOS 3.8b15 without the STAC
cards? I ran b15 for a week with the cards in and received many complaints,
mainly from 33.6 modem customers who though connected at 28.8-31.2 they
would timeout on html pages. They seemed to not have any throughput. So I
went back to b13 now of course my v.90 users are screaming cause they loved
the great speeds they were getting (46-50K). Does the STAC cards benefit
my non ISDN customers?

If the STAC cards do benefit most of my users then how do I have users turn
off the stac compression from their end, client side?

Or if this is a known problem and I should wait please advise cause I've
been monitoring this maillist and have not seen anyone really with my
problem SOooo I figured I just may have something I need to fix.

Thanks for the help.
C-U...
