I've done that before, and it doesn't seem to have destroyed my DPF or anything. I ran it for a day or two. I also have run the 150 DPF delete tune with the dpf on. Same thing. Once I got the DPF off, it lowered the back pressure a lot obviously. I have returned it to stock on occasion (after installing the DPF) and it went into regen the first time I drove it stock, then it was good to go (as good as stock is).
I would suggest returning to stock and drive it a few miles to see if it wants to regen. Then if it doesn't, go ahead and remove the DPF, and put the 210 tune back in. If it does, let it regen, then remove the the DPF and install the 210 tune.
That way, if some thing terrible happens and you have to install the DPF back on the truck and it doesn't drive for some reason (say like a bad HPFP or something) it will have a clean DPF. That way the dealer won't whine about there being something wrong with the DPF, and not find the real problem.
