Cupra not boosting right !

[t111bul]

Hi, I own a 2001 Ibiza Cupra that's been re-mapped . My car spikes to 1.35 bar then drops down to 1 bar but this week my car seems to spike to 1 bar then drop back to .6 bar, the problem is that it doesn't always do this . I've spoken to a garage and they seems to think it might be my MAF gone wrong again .
Has anyone esle had the same problem ?

check that you haven't got any of the 'small' pipes split on the top of the engine

as mork said, check vac hoses

also check intercooler piping, i had a problem similar to this and found a whopping hole in my intercooler piping where it had been rubbing, welded the hole back up, extended the pipework so it didnt rub and happy days

i av the same problem my boost is all over the place. i have a 2001 mk3 ibiza cupra and had it remapped by awesome gti, i also had a new maf sensor cause old 1 was broke and i was loosing 10bhp. once new 1 was on it was fine. but just found out its gone again and its only 5 months old. i also got some 3mm silicon hosein for pipes on to of engine cause they kept splitting under the pressure. LOOKS LIKE ANOTHER TRIP TO AWESOME GTI!!!!!!
