stage 2 is notorious for shitty timing and a lot of fuel....
i'd junk the stock boost guage as quick as possible.. after getting an electonic boost guage (w/zeitronix) i have found that the autometer guages (stock or 30-30) are quite off (in vacuum and in boost)...
map clamp will lean you out, however, you should have something to add a lil fuel up top (i.e. return line or afc).. cheers
