Is A Remapp Needed

[wrxcook]

alright you all im driving a 2003 wrx ppp, im looking to dress up the engine bay, the question is if i replace the pulleys with light weight anodised ones does this affect any thing else, also where is the best place to buy alloy tanks for the engine bay for this year of car as i can only find them for classics

No, you'll be fine changing the pulleys.
