Just another boost problem
 

Hi
Have got an intermitant boost presure problem,
have done a vacuum hose job wen i got the car and has been fine for ages.
Now sumtimes is will only boost 6-5-6. the next day it will be 11-8-11.
i understand it can be a loose hose but have checked them.

mods are cat back and hks filters.

could it just be a loose conection on a soliniod.

not sure if temp is anything cos today it was fine when i first started it and then a bit later when it was hot it was up to its tricks.

anybody got any ideas

your wastegates might be getting stuck open, air temps matter but you are not going to loose that much boost, check to make sure that your vaccum lines have no cuts in them there might be a leak that expands when hot...not sure if that is the problem but it is some areas you can check.
