sounds like you have more than one problem, if you are loosing boost most likely its a vac leak somwhere... hard to find, since you seem to know what your boosting you should have a boost/vac gauge, what is your vac at idle?
for your car dieing when you put the clutch in/reving its probably the EGR valve getting stuck...there is a how-to to fix it in the how-to section...its not too hard to DIY just a PITA to get to
blow into the vacuum line that goes to the wastegate, if you can blow in then the WG is the problem, let me know.
good point...Wastegate is always a problem but I think overboosting would point to WGA not lost boost
so ya my vac and boost seem to be fine at idle but i think the bpv might be bad b/c it doesnt even turkey anymore it jus like sneezes... but im pretty sure the egr should fix it... im gonna try to clean it and i hope to god that fixes it b/c its pissin me off lol... thanks for the help ill let u all know if i can get it fixed...
so i took the egr off and cleaned it the best i could wit brake cleaner and still didnt fix the problem... if i keep the heat or a/c on full blast it stops the problem... is there ne way it could be the throttle positioning sensor goin bad? if not wat else could i try? i need help here ppl so give me ideas... thanx
did you check the Wastegate?
not yet but i dont c y that would cause the idleing problem... im not exactly new to the turbo but im slightly undereducated about it... and this is my first turbod vehicle so im tryin to do stuff on my own to learn and get aquainted
one of my buddies mentioned that it could be a throttle positioning sensor?
albeit I am not a mechanic, but I do know my way around the FS-DE (to a certain extent) and the common problems with the MSP, I don't think I have ever heard of a throttle positioning sensor on this car....(uhm)
like I said in the post above, I would check the WGA (just because you never know) and clean your MAF to see if it helps
don't clean your MAF with break cleaner, clean it with rubbing alcohol and make sure it completely dries
good precision...I think there is also a MAF cleaning solution that seems to work well...can't remember what it is though

Yea, i got the same problem as well and i cleaned my EGR twice in a row. can the EGR valve itself go bad? i took mine all apart and theres a little piece that screws into the middle of the EGR internally. it soesnt seem to seat tight when screwed in all the way and the threads that it screws into are plastic, possibly stripped for some reason. So i might get a new EGR valve somewhere....im going to check the wastegate first though. Can a EGR blockoff plate be installed?

yea at the part store they have maf cleaner or if they dont have that you can use electric part cleaner

I had a similar problems when my bpv got disconnected. I think it just a vacuum leak...do you have the stock ic pipes? If so...check around the bpv. It's as simple as that but takes abit of time to locate. Goodluck!
ya i took the egr off twice and tryed it and im still gettin the same thing... not only that but now im getting a violent jerking when i go to get on it. idk im stressed to the max right now... i loved the car for the first 2 weeks now im starting to ****** hate it lol
