Ok so the stock power from my 91 turbo capri is a little boring i picked up a garret t3 a universal 21/2 front mount kit and a custom manifold in the works i dont want to go full standalone but i have read there is a guy that does rom chips for stock b6ts my problem is if im running a larger turbo i feel its going to need a little more than just a premade rom chip has anyone els done this?
