I have a boost problem that seems to be getting worse but I just can't find it When I put my foot down the first turbo usually boosts to about 11psi but lately it only boosts to 9psi and then when the second turbo comes on it boosts to 14-15psi but it usually boosts to 16.5-17.5psi. This isnt the only problem because when Im crusing along and plant my foot, the auto drops a gear the engine hits high revs and then I get about 3psi boost now it used to do this but not that much but its getting alot worse now. If I left my foot on the loud pedal until it chaged gear it used to boost normally but now even when it changes gear it still stays at 3psi until I take my foot of and plant it again, even then I have to try a few times to get boost again. What could this be? Could it be more than one problem? Iv searched for loose hoses but couldnt find anything in that department, Iv read it may be the EGCT (I think) but how do I tell?. This problem is getting worse and annoying because its making my car horrible to drive I dont even like to try and overtake now . Any advice would be appriciated, I would really like to get this solved. Envy isnt far from me but I would like to see if I could fix it myself and save alot of money if I can. Thanks guys.
