It's all in the build, and the tunning. 6lbs can vent your block just as easy as 26lbs. But one thing that I have noticed, is the stock plastic intake mani has some cheap ass hose clamps, and I've blown them off before, twice in teh last 3 years that I can think off, but nothing damaging, just rotine maintance, and check it every now and then.
