More mods????
The standard difference between 1's and 2's are the nozzle size... For the most part, 1's have stock nozzles and 2's have 80 or 100% over stock nozzles... I would get yours rebuilt with new internals... That's what I did... Of course, new is always the best option...
I've read there's like a 50-100hp diff between stage 1's and 2's. People usually dyno (with supporting mods of course) around 300-320whp w/ stage 1's, and stage II's usually put you closer to 400whp. Stage II's = more fuel in the same window.
