Well fortunately I was able to find the issue, it was the software, I borrowed a dme from a lister from another 2.8L rogue tuned 951 and the idle and AFR are perfect.

Did you try loading the base map .bin into your DME Tuner, or just swap in the other DME?

also tried messing with some things on the tune, and under the hood, couldn't get anything to work. ISV disabling at the diag. plug and by unplugging it, o2 sensor, wiggling wires and hoses etc

Josh the other dme is just a regular 28pin dme with your chip, the only way I can have that bin file is if you provide the file to me since you put it on that chip

I can pm you the customer name is a fellow lister i would need the last program that you burned in his chip, also what I noticed is the car goes like in overboost protection once I hit 10psi, do you think this could be a bad map sensor?

we downloaded the "base tune" files off your website and uploaded them to the DME that came in the car without any change in how it ran...it would idle in a 400 rpm range (900-1300ish) or so and if you revved it up the afr and tach needles would dance around even without moving your foot at all

Also, send me your shipping address, I'll send you out a replacement chipboard.

Stupid question, the previous owner of the car had set according to him with the maf tuner software a limit of 10psi, but by installing a new dme with setting of 17 psi wouldn't that override the first setup, where and how you limit the psi? with the software?

There is most likely an issue that the software is trying to keep the motor from hurting itself.
