hey i have a boost problem with my 95 jdm rz

dont have a boost controller at the minute

have it de-catted with restricter ring

 

was boosting a little over 1 bar for weeks then the car was parked up for a few weeks

 

now the problem is, full boost will come on and if i left of the throttle it will drop off to about .5bar and wont come back up until i push the clutch and let of the throttle for a second or two and repeats like this.

 

any idea what the problem could be?

air leak, vsv on the way out etc

 

thanks

steve
