new pump, need a reflash?

My stock lift pump died, so i called the dealer they had a conversion kit oem mopar to covert to intake pump with the whole harness etc. Install went very easy, but the last 2 pages are with reflashing the ecu. My question is the truck runs drives seems to have same power, Should i get the ecu reflashed?

I wouldn't.

What year, do you have any mods? Have you ever had the computer re-flashed?
