Default dumpvalve delay

i know there not liked much but it's my first turbo so i like it. how long of a delay should it be before it kick in. because whan i change gear on mine i takes a second or two to kick in is this normal? i thought soon as you take you foot off it kicks in or is this for heavy modded engines. the bigger the bhp the quicker it kicks in?.

the car is a standered erst s2

how slowly do you changes your gears?
it should be done in 0,5sec

i noticed on my cossi
if i close the throttle very slowly-its not
engouh vacuum to open the dumpvalve .
it opens 0,5sec later-you can hear it chatter.

you have to close the throttle fast to get
vacuum on your dump valve.
how thick is your hose diameter?

i use a baileys 2pistons valve.

it deppends on how im driving it if im giving it the bollocks i change as fast as i can. so am i liklly to get a bit more preformance by letting it kick in a bit or will it make no differnce. iv only been driving it for a day and a half so still getting used to driving somthing with a turbo on it.
