hi im new to this site but it seems brilliant

anyway havent had the car long and i think i killed the 1st engine with a man boost control valve so 1month on and a reconed engine ive disconected the valve now put the pipes where they should be and went for a drive thing is shes over boosting to about 1.4 bar and then the dreaded brick wall fuel cut happends cant understand it as the car is now standard oh yer and i removed the chip and reset the ecu
any help would be gratefully received thank you.

 

Give the boost solenoid & pipes a clean with carb cleaner

 

Little bit more info on the car would help (year etc).
1.4bar is way above any standard ecu fuel cut.
I would guess you may be missing a little brass restrictor in the boost solenoid pipes.

 

thank you
your help has been spot on
