just had my car mapped on firday and it made 204 at 1 bar on a safe map as the radiator decidied to give up and start leaking so they couldnt map it at high boost, but the cars been fine until sunday night when i was driving to my mates house, was fine for the first 10 miles boosting fine then gradually the max boost dropped until it wouldnt go past 0.3 bar, all vacuum hoses and boost hoses seem fine, have a feeling it might be the wastegate spring as they said it seemed a bit soft when they mapped it, but could it be anything else? thanks in advance
