Exclamation Gear change = power pause

ok i give in.


ANY suggestions on what to look at will be done!

My car has started to pause b4 giving power when accelerating through the gears. once in gear its fine you can put your foot down and it goes, But if you then change up there is a pause of about 3ish seconds and then it accelerates again.

Please help . I've tried disconnecting power for an few hours to reset but i dunno maybe it needs plugged into puter and reset? bought an u581 reader but wont work with this car.

previously i tried hooking up a greddy profec boost controller but couldn't quite get it to work properly as the solenoid valve won't work quite right with a vacuum instead of positive pressure. One thing to note is though at no point did it boost or spike more than is does as standerd. there is now a lag in boost preasure that mirrors the acceleration lag.

I've been round all the pipes and made sure there tight as i thought maybe there was a small vacuum leak causing the waste gate to take longer to shut
