car running to rich on bank 2 around 10.0-13.0 a/f ratio

I just finished my car with full bolt-ons with long-tubes and got Ortiz to tune my car and my car was running amazingly pulled so hard it and a/f was on the dot all the time. My car ran amazingly for 2 months then my a/f full would hang around 10.0-13.0 at wot, idle, and normal driving right after started. but after about a mile or two it straighten back out almost to normal and then sometimes it will usually does this again in the middle of stop and go traffic maybe or sometime random. I data-logged and showed my driver side was running rich. I replaced my stock maf with a 90mm lightning maf, and I switched around my o2's and still nothing for now we tuned my o2's to open loop for now to get my a/f ratio back to normal. but what could be the cause of this my bank 2 o2 is pegging at .750 when bank 1 is at 1.0-.9 anybody have any ideas?
here is my data-log if anybody cars to give it a look and maybe some techno nerd can see what is going on.
