Most nitrous problems aren’t “nitrous problems.” They’re sizing and consistency problems. The simplest way to keep it repeatable is having jets and nozzles you can actually trust and swap quickly. Our nitrous section has Big-D jets in both -6 sizes (.067–.315) and -4 sizes (.023–.160), plus matching nozzles so you’re not mixing random stuff and guessing. It’s a small parts list, but it’s the difference between “same hit every time” and “why is it different today.”
