NCTRX Build Complete....for now ;)

I don’t know anything about boost or engines. Is 15 the max even if you get a completely better bottom end?

You can run 21 lbs on a stock engine with a good tuner and the right mods. Anything above that and it’s a ticking bomb. Some will say more and some less, it really depends on mods, tune and how you drive it.
