One thing to point out, is that I also contacted OFT support. Their support team mentioned that they 'disable' some codes while on Stage 2+ tune. Im not sure why they do this. I think that if those codes where not disabled, i could have found the problem much faster.

That makes total sense in your case with your catless setup that the OFT flash would have disabled that code from triggering a CEL, and should be something that users of the product should probably be made aware of before using the product (if they aren't informed somewhere already). I've got the rear O2 sensor failure related codes disabled in my flex-fuel tune through EcuTek. Sometimes in order to make a gain somewhere, you may have to make sacrifice somewhere else and we have to live with that and adjust to it as best we can.
It's threads like this though that help us all learn how to overcome issues that crop up when using aftermarket tunes. I'm glad you were able to get back with us with the final verdict. And glad your twin is back on the road playing nice.
