Couldn't find via search so here goes planning on boosting have an auto. Plan is boost then save for a manual swap. I have a place that has done some so I know general ballpark pricing. My question is can I run a kit for a manual swap springs on wastegate for lower psi or do I need to run a kit for auto.

 

you should do the manual swap first.

 

if you buy a kit like dezods, they have a couple things that are different between auto and manual kits. (ic pipe routing or oil return line iirc) and if you boost auto first you'll need to buy a tranny cooler, which will just be more money. so i say swap then boost.

but to answer your question, yes. you can ^^
