i have a VERY frustrating prob :(

when im going aprox 70 mph and do a kickdown there is no boost it just sounds like im torturing the car..

but if i build upp little boost before i hammer the throttle it rockets away with 1.0 in boost. this is very disturbing becouse when some ricer comes screaming on the higway i slam the throotle and nothing happens and the evil ricer gets past me.. :(

 

soo please help me because no soop should be overpassed by a civic

sound similar to what a few have had. It's usually due to a dodgy vsv, which isn't allowing the second turbo to come online. There are four which opperate in the sequential system. Test them all and see if you can find a dodgy one.
