I may be wrong (again) but I think that the throttle plate has to have some gap when closed, it can't be shut all the way. That is how needed to set up my TMax, but it was a few years ago and I don't remember the spec on it, but it was very small. Maybe it's only for that tuner, but it's possible the adjustment changed on your blade.

You may just need to reinitialize the ECM to the new TPS sensor. With the run / stop sw in run, cycle on / off to on 30 sec, off 30 sec, on 30 sec, off 30 sec, on 30 sec, then back off. Should reinitialize the ECM.

Good advice. Start there. The TPS is just a glorified potentiometer (think dimmer switch for your house). It gets 5V in from the ECM and spits 0-5V (ideally, but more like 0.5V-4.65V) out to the ECM to tell it what position it is at. Would make sense a new TPS might have a different range than the old one.

thank you guys so much! i will post up my results when i get home tonight and turn some wrenches. thank you for all the feedback! i was a bit lost where to go from here!
thank you all so much for your help... we are fixed... but took some hunting... pulled the plugs and replaced them, removed the wires and cleaned all the contact points very well. pulled the throttle body out, cleaned that really well including the injectors, every plug, and lubed cables, checked butter flu on warm/start up... still did not fix the issue after it was back together... so i then started to chase lines... pulled the battery and box out, and found a very small tear in the wire harness, cut that open to discover the reason for my codes!!! re soldered the wires up, wrapped it, and put it all back together.... again... and she is right as rain! thank you again for all the help and getting my gears turning to figure this sucker out!

Happy ending. It's gotta be a relief to find something that positively caused the problem. Not always the case.
