I have an EK with a GSR, and after talking with a few people, some reccomended a t3/t04e 57 trim/.63 ar(precision sc34 or a garrett).. but then others said no, because of lag (full boost at 5300~)

It made sense, because my car barelly sees 5k on a daily basis..

Anyone have any other suggestions? I was shooting for 250-280whp~
