Default Retune after installing walbro 255

Would there be any reason to retune my car if i install a walbro 255. I had a walbro in my car and drop it off at the tuner and the pump took a ****. So i had to reinstall the stock one for the tune. It made good hp on the dyno and had a good afr on a 125 shot of nitrous. Will changing it back out for a new walbro mess anything up in the tune?

It should not make a difference in your tune unless the tune compensated for a pressure loss due to an insufficient pump originally.

Will installing a Racetronix and Hotwire harness cause the car to run rich ?

Sorry for the redundant question but I can't seem to find a definative answer.
