having a 450 capable engine running 250 hp is gona run rough as guts and sillie on the streets
with your turbo i think probably a good choise really 450 hp is good for dyno and drags ur gonna make max power like between like 4500 and 7000rpm so lag don't matter on dyno but maby an anti lag system when at the drags?? idear i don't kno ahahah
