sorry, another noob-ish question,

i have boost by gear, in 2nd-6th i am at 15 psi, and in 1st i am at 13

is it easy to just change the boost in 1st to 15 psi? if i have to extrapolate the maps and do a bunch of other stuff, i'll just leave it alone

any insight from more knowledgeable folks is appreciated! thanks!
