Code P0234

Found this code today, it means turbo boost limit exceded. This is because I have the wastegate pinched off and I can reach 25-27 LBS of boost now. However I dont have the edge comp in my truck as of today. My question is, when I reach about 25-26 LBS of boost it seems like the truck falls flat on its face... Is this because the computer is de-fueling the motor without the edge installed??? Thanks!

Yes. More boost without a boost fooler/box/Smarty will only tell the ECM to defuel and set a code.
