How far are you driving it? When you say remove the dpf, are you going to decore it/put a straight thru pipe on or just have a missing section for the drive?
From my experience, the car will think it needs to constantly regen about 10 mins into journey, you've then the most horrendous amount of acrid smoke pumping out the back until you park up and cool down. If you've Multiscan you can reset the DPF so it thinks it's got a new one, I got a smoke free 250 miles by doing this, not sure how many more it would've gone for, but I had Mscan in the car with me anyway so could've reset it.
