boost

[GT-POWER]

i want to ask something my friends
my starlet gt doesn't hold 1 bar, it drops off. what can i do to work all the time 1 bar with no drops off or overboost

Is it running a stock CT9? if so then you can't get it to hold full boost all the way to the rev limiter, you can get it to hold to about 6200 around that area.

Its very normal for them to start dropping boost before 6k revs.

is something to make to not drop off?someone friends from england said me to remove the a/c and then put the air filter at the front.

Yeah he has a ct9 Nick. I've told him in the UK we remove the A/C and front mount the air filter but in Cyprus thats not really an option. His boost drops from 12psi to about 9psi around the 5k mark. Seems to be dropping a little early. Apart from front mounting the air filter what other options does he have?

loose the air filter and mesh the turbo??

Similer issue as me, boost up 0.75 then stay steady around 0.65 after 5500rpm. this is all stock but is spools up much quicker
