will running bigger injectors require an aftermarket adjustable fpr or will the stock fpr be ok with 880cc's and a walbro?

Sure stock fpr will work. Adjustable FPR is great for fine tuning on bigger injectors. Adjustable fpr benefit greatly on small and mid size injectors to add a little more pressure so it can increase up to 30% flow from stock. GL!
