So im have an evo 8

evo 8 or 9 turbo in it idk what it has but its at 24 psi and makes 324awhp
ported mani/hotside
offbrand tbe
stock fmic with uicp but ams licp
walbro 255
???? injectors
stock block and head
so it made 324 with those things on 24psi

Now im going to have gscs2 cams and beehive valve springs
what kind of increases am i looking at? ive heard of people getting 60-80 hp from going with bigger cams.
also should i get a bigger fmic at some point would i notice a diffrence?

Thanks.

 

such significant gains are usually with a much larger turbo.
A bigger fmic would cause some turbo lag but would increase turbo efficiency & you'd be able to run more boost.

 

i went to a 3.5 ETS FMIC, no loss in spool to the butt dyno.
