That is not a real number for the STFT. If that number was correct, it would mean it is adding almost 100% fuel to get to stoich which isn't realistic.
You should be getting a STFT and LTFT number. The highest LTFT number you can get is +/- 25%. If you had tuning software, we would get you running in no time. It is impossible to tell what is going on without a log of the engine running.
Does the tuner have the truck in open loop or is it not running long enough to raise the coolant temp. The STFT numbers won't update until the coolant temp is around 130 or so. If you could get it to run long enough to warm up, the fuel trims might take over and let the thing idle.

so the issue ended up being i bought FAST 57's. the tune from wheatley was for 60's. not that its a big issue but the injectors according to my tuner are acting like 44's. he had to cut ALOT of fuel out to keep it running. apparently the 44's will work just fine but if i didnt get the injectors i paid for im going to be pissed. once i get the valve cover clearance issue worked out ill pull the injectors and see what number are on them and confirm what i got.
