rich at idle and cruise for no reason using E85

[jesse_fc3]

Relevant car info:
2g AWD 5spd
E85
new fuel filter within past 2 months
dsm link chip but no laptop to tune/log with (i use my friends when i can)
maf-t GEN II
650cc injectors 97% idc's @19lbs on a 18g
255 pump
I've been running this set up for several months now and its been running great.

One day out of no where i noticed my afr at idle was super rich (11.1:1) and it was so rich in the top end under boost (10.0:1) it was cutting out on me. I tried to lean it out using my maft gen II but afrs won't change. I can hear the motor bog down once I start leaning it out but afrs stay the same and under high boost it kept cutting out no matter how much fuel I took out.
I then switched from E85 back to 93, now I can change my wot afr but still not idle or cruising afrs they are now stuck at 12.3:1. I can still hear it bog and start missing when I lean it but afrs stay at 12.3:1.
My mid range, I never had a problem with tuning.
I'm thinking maybe my high idc's are to blame and it's my injectors expressing their hatred for me. I know I need to get some 1000cc+ injectors, I just haven't had the extra money yet. I've also been wondering if the infamous black beard is to blame, I haven't had the injectors out to look at them yet.
Anyone have any ideas?

Did the car drive fine before and after you noticed?
Did you do anything or did anything happen to the car prior to you noticing?
First thing anyone will say is, did you do a boost leak test?
How long have those 650s been running e85 and how long has your IDC been 97%?

Good God, you have two seperate tuning solutions fighting each other.. PICK ONE!
And you're running what would be similar to a 450cc injector when you're on E85, no wonder you're maxing it out with an 18G..

1:I didn't do anything to it just one day i noticed it was rich
2:No nothing happened and i didn't change anything
3:No i didn't do a leak test recently but its pulling normal vac and i have a gm maf so a leak in the ic pipes wouldn't cause a issue at idle
4:As i stated above I've been running this setup for several months now (4-6mo.?)

several people run link with a MAF-T I pretty much just do timing, global settings, launch control and logging with link and do the rest with the Gen II so nothing i do with one is trying to be corrected by the other. And I said I know I need bigger injectors, like 1200cc's, but I'm going to beat these until i have money for some.

What I need to know is, is my issue a sign of injectors failing? I've never ran into a bad injector before.

I reset the ECU, re-tuned it on link and the car runs great now I don't know why but it does, thanks though.

Whoever told you to set the base fuel on Link ans tune with the MAF-T is wrong on so many levels. That's completely backward. Reset the MAF-T back to completely factory settings and tune 100% with with DSMLink. All you'll need to do is set the MAF settings in Link to either 3" or 3.5" MAF-T depending on what size you are using. You should have no settings whatsoever on the MAF-T.
