i call upon ur help again people!! I have a mbc on my car, set at .75 bar (by the boost guage). however i keep losin boost. some times I put me foot down and i can feel it hold back and it only reads about .6 bar on the guage :cry:

! im so frustrated with it :banghead:

. I can have a play about sometimes, take pipes off and refit, and then it may b perfect! for a week mayb! so may b its jus luck and coincidence that it starts workin? ive checked all the pipes time and time again! i do have my suspicions about the mbc. in all honesty i want 2 lose it and fit an everest chip from alan, but i want 2 get this prob sorted 1st! so any of u elan pros got any ideas 4 me???
regards
matt

Think with an MBC u have to disconect the BSV back of the airbox :idea:

sounds like a sticky wastegate. there are write ups on here on how to fix it.

right then i ll check the wastegate 2 day, cud it b a faulty actuator??

No, not faulty, just sticky. They can be freed-up pretty easily with mole-grips, and if I remember rightly, Stevo himself did a good write-up on how to do it. Just do a search for all of his posts and I bet you'll find it.

well ive checked the wastegate and it moves freely :cry:

I wanted it 2 be stuck!!! :evil:

now im bak 2 square 1! what else cud be causing this drop in boost? cud my turbo be dead? it doesnt smoke or anythin? and it works fine apart from this prob!!

Check all the pipes going to the MBC etc, maybe there`s a fault with the MBC, take it out and go back to stock and see how she goes

i agree, put it back to stock and see how she runs. then buy one of alans chips, i seriously recommend them.
