as above, it prob wont raise peak power much if any, but will give a broader power band,
the .63 isn't realy that laggy, but it is a bit more than your current turbo
i dont think you'll see anymore power without a turbo change, as its currently a limiting factor,
but a decent set up/map will prob make te car feel faster so well worth doing
cant go wrong with reyland, martin will keep you right
