Did the problem perhaps start right after you installed it?
I do not believe durametric will help you in any meaningful way compared to generic OBD2 adapter.
I might be wrong but your ltft's are that negative and I assume your Fuel pressure doesn't drop when engine is off.
My guess would be it's MAF related.
What does your MAF read idling with AC on and off?

fuel pressure stops at 48 psi how do you check the fuel pressure regulator and vacuum diagram any idea ?
to be honest car seems to idle and run pretty good for the most part and Think I was dealing with
OXYGEN SENSING CODES BEFORE AND I DID NOT checked LTFT previous to the new air
intake from BB performance I also got a chip module from them ( big mistake on the module
BEWARE ) car would NOT even start after wiring this module to the CTS according to
instructions , removed it sent back to them from globalautoshop.com
waiting for my refund ..
also I did replaced the upstream 02 sensors and I got a new MAF sensor exactly same numbers as the OEM bosch one , NEW STARTER TOO
I will check the MAF reading with a/c on and off I m using ICARSOFT POR 3 to get the date
