Default Fuel Trims, Tuners, and Cat Removal

Does anyone know if the Flashpaq has the ability to compensate for fuel trims after the cats are removed? I took the cats off my truck and it gets near nothing when it comes to fuel econ. and it smokes now, too. I tried the anti-foulers that Randy mentioned but it didn't seem to really help that much, beside the fact that I get slow response codes now as well. I tested the o2s's and they are reading 0.9 v. to 1.0 v., but the scan tool reads from 0.0v to 0.25v which leads me to believe that the engine computer translates the signal to whatever the manufacturer programmed it to. So, that is why I was wondering if the the Fashpaq or any other tuner/ programmer can "change the translation". Any help is greatly appreciated

P.S. I would like to get a tuner, but what is the point if I can't fix fix my current problem?
