You heard a Quad Stealth stacked with Juice that had no timing? That should be less noisy than the same stack that both have the timing.
The Quad all by itself is noisier than some of the other mods but a powerstroke noise it is not. It is just a sharper diesel rap than stock at some areas of the powerband but it is not a rattletrap school bus like a PS.
I have been running the Stealth 215 and HJ 125 stack for a while and thus far has not posed any isses with too much timing.
