i replaced the dv because i wasnt getting the boost i expected to see, i have an 01 225q and am only seeing it hold 5psi and spike to 10-11psi. the forge dv def made some difference in spool time and boost recovery, but it didnt change the max boost i saw, so i assume i have a leak somewhere. i know i couldve flipped the bosch dv(thanks cicny) but i know i want to chip it later so i replaced the dv anyways in case that was the issue, apparently its not. i dont have a compressor so i dont know that ican check for leaks that way, other reccomendations? thanks.

 

thats the normal for a non-chipped 225 but it should settle more around 8psi....green spring? replace all your vaccum hoses....get the starter kit from hose techniques.com you will have plenty left over

 

I have the red in their I believe, whatever one was installed default since i'm unchipped. Thanks for the advice,I will check the kit out. I had in my head that I should be seeing up to 16 un chipped for some reason.

 

get that red spring out asap!!! it will damage the turbo!!! red spring is the strongest spring!!! made for high boost apps like 30-40psi

 

i biked to work so ill have to check later for sure: :P for the 225 unchipped, i should have the yellow one or the green? green for 5-15, yellow 15-23psi? oh man [8D]

 

Just stick in the yellow and if you chip it later, you may only need a shim.
