Hi all im having a problem with the cupra....my car will spike at 21-22psi and hold a healthy 18psi. Ive swapped all my hose clamps on the car for even load clamps with worm gears on them....i doubt its a boost leak but i havent had chance to check yet. The symptoms are when im giving the car full boost she'll get to the 21-22psi and not want to hold the 18psi and just tail off to 7psi and stop there (limp mode?)
Ive had a read and it does sound like a boost leak sort of but like i say i doubt it with these new clamps...fuel filter also came to mind...maybe bad fuel delivery at high boost? i got a fuel filter when i brought the car so maybe its due a change?
any help is appreciated
