I have twin modified Danville pumps on my lbz right now and I was curious if I change over to a single 12mm or 14mm pump if there will need to be any tuning changes to the regulator? Also, how much difference in fueling will a 12mm or 14mm pump provide compared to the twin modified pumps?

It will all depend on the truck itself and the combo as to how it acts. Things like lift pump pressure and fueling quantity all play a role in the numbers. You will have to put it on and see how it reacts. I would do a 14mmcp3 from Exergy if you are going from two of my modded LBZ pumps. The single modded LBZ will do 600-650hp so that's 1300hp for the pair and a 14mmcp3 is good for well over 1400hp by itself since we have seen 1380hp at the crank on a single 12mmcp3. Hope this helps!
Curious as to why you want to go to a single pump? Just figured id ask since the 14mm is 3k$ and you already have the dual set up. Also if you decide to sell the kit i may be interested in the kit with a modded pump.
Single pumps are easier to tune, less to go wrong, and do not rob horsepower like duals do.
