boosting

hi , ive just bought a ibiza cupra , photeks old one , and adam k s old one so ive been told , when the car comes on boost it goes upto over a bar then drops to 0.5 bar within seconds , the car has got a print out for 217-219 bhp , but it feels more like 160-180bhp , any one had this problem

My car quit boosting the other day so i had a poke around and ended up replacing the hose that goes from the N75 to the charge pipe (hose had a small wear mark but that was it), problem fixed instantly. Now tonight i start the car and again, no boost, not even 1 psi. Car was fine when i...

Car usually peaks at 1.5bar and holds at 1bar. But today it will not peak past 1bar, its felt very sluggish for the past few days i was suspecting MAF. So tried unplugging it, but still peaks at 1bar, also borrowed someone elses MAF and still no difference. What else would cause this...

Right get straight to the problem, my mate Ibiza Cupra keeps over boosting. Ever since hes had a bigger turbo fitted, its been a pain. Ive asked him for a list of the things thats added to the engine, its a 1.8 20vt cupra. Its had alsorts added to it, turbo boost controler etc. but still it...
