I can't speak from personal experience,.(i.e. I haven't done the pulley thing yet) but from other posts that were put up, you should not have to have the chip re-programmed. I believe Mike from superchips said that only if you do something radical like adding a supercharger and/or nitrous oxide will you need to reprogram.
I'm 99% sure this is correct advice, but maybe others will reply....

Hi Skinny,
As the others correctly pointed out, you do not need to change anything in your powertrain programming (Superchip) for the use of things like underdrive pulleys or going to an electric cooling fan, for example. Both of those modifications simply reduce parasitic losses so the engine doesn't have to expend as much energy turning the various accessories, which in turn frees up more power to the rear wheels.
In general, it is things like changing the MAF (mass airflow meter), superchargers, nitrous oxide, ported cylinder heads, camshaft changes, changing the size of the fuel injectors, gear ratio and/or tire size changfs in the '99 & up units, and sometimes headers are the basic types of kinds of things that will require custom programming in these late-model F-trucks.
Things like a low-restriction air filter, an airbox kit like the Air Force One or K&N's FIPK kit, etc., cat-back exhaust systems, underdrive pulleys & electric cooling fan(s) can be used with no changes to the Superchip, as a loose general guideline in these F-trucks.
