None as long as the bottle pressure is the same and fuel pressure is the same..

Anybody run closed loop O2 while on nitrous (with a UEGO sensor)?
Never for me just a poor idea.

Not if they are high quality parts. I would not run it for 3 miles though unless
you have a lot of money and engines to play with. Actually it all depends on the
speed of the car at 300 mph 3 mile is a much shorter time than at 175 mph.. For
anything more than 15 seconds there can be a lot of hoops to jump through
technically. Also a kit that is more than 50% of what the engine will produce
with out it can be problematic at best. At 25 to 30% it is pretty simple to use
for short durations like the last mile of the run.

If you search the archives there are a few good threads about this subject.
