Re: Over Boost
 

read the thread before yours, because your probably having the same problem as me, so read it... check your MBC, if not that, then its your wastegate.

Re: Over Boost
 

I would do a boost leak test and make sure the wastegate is opening at the pressure level that it is suppose to open at.

i have tried everything i know how to do i am not a turbo person this is the first one i have had and well what sucks is my moms funeral is tomorrow in grand rapids so i am desperate for help with it i just dont know what to do anymore i think something is just not hooked up right but i could be wrong

Re: Over Boost
 

if i were you just be easy on the car, drive slower, and try not to boost the car, that's all i'm doing right now, well until i fix my little problem.... and try to work on your grammar, I still have this problem, but damn dude.

Re: Over Boost
 

well actually i fixed my problem i had unhooked my bov from its vacume source and my car is running perfect very wierd but cool so i am gonna go drive itg for a bit and see how it does talk to u all later

Re: Over Boost
 

Wow unhooked your BOV. Thats new. Well here is the deal...your BOV should have one line running from the intake Manifold. Not off the TB but the intake. Your wastegate line should come off the Turbo outlit pipe on the downpipe that runs to the bottem of your MBC then another line runs to the Wastegate it self. Thats how you should have your vac lines run. Go to www.vfaq.com for photos. Hope this helps.

Re: Over Boost
 

I would check all your vac line routing and if it still does it:
run a line from the compressor housing to the waste gate, if it still runs to much boost check your waste gate actuator with a pressure tester should be full open in the 10-15psi range. If all that does not fix it then you need to port out the waste gate hole and/or try a different o2 housing (either a LIPP or similar).
