I Just had the cam belt, tensioners, water pump, auxiliary belts etc changed and although the car seems to run perfectly, when you floor the accelerator the turbo boost shoots to around 14psi (US model) then it drops to around 12psi, then back to 14 again.Sometimes the boost stops at 9psi, pauses then jumps to 14..then back down to 13psi and so on. It´s not just the boost gauge either as you can actually feel the "slight" hesitation. The Turbos sound fine too..anyone got any ideas ?

 

cheers

Do you have a boost controller or boost jets?

Do you have a boost controller or boost jets?

 

Hiya TurboZ

 

No I don´t mate, niether a boost controller or boost jets,as far as I am aware it´s 100% stock.

check your wastegate actuator feed piping for tightness/splits/obstruction/jets.

 

(small hose on both sides under main boost pipes)

I went and had a quick look, they seemed fine at first glance but as it´s about minus 3 out there it really was a "quick look" I´ll do a proper check tomorrow after work. Appreciate it

check the wategate solenoid connectors on either side of the engine as well , they might of been disturbed and not put back properly

Thanks Retro, I´ll check those too ,appreciate the help
