i have got a boost controller its a gretty profec b spec 2 i got it installed but they didnt install it right it was pushing 4 psi i put a manual one on and out of first it was regular but then out of every other gear it hit about 17 then just went back to like 5 psi when i was on it now it got re done and now its pinning 20 where do i put the hose that says to go to the fuel pressure regulator i think thats my only problem. please help

 

i have no idea what you're asking here. so you have a mbc, it's spiking to 20 and droping to 5? do you have a wga? how are your lines hooked up? sounds like you have no line to the wga and it's running off the spring, which on a stock car is about 7psi.

 

i hose line from the wga to the boost controller theres one to a vaccum and the other one to another vaccum i think, but in the manual it says to hook that last hose to the fuel pressure regulator but there isnt one on an 05 srt4 so where would i put that hose? and it aint just spiking its really pinned down to 20 till i let off it back fired on me to i dont know what the problem is every one has said they dont know very much about the srt4.

 

i still am just not sure what you're talking about. we need to know what lines you have things hooked up to, just saying a vacuum line doesn't help at all.

here's a link to a how-to for a mbc, take a look at that and see if that helps you at all. MBC Install

 

im with PSIChick on this one. Your posts are confusing.

 

sorry i dont know to much bout this stuff but its an electronic boost controller not a manual one. one vaccum line comes from the 2 and the botton hose part of the solonoid that had like a little breather on it on 04s there is a green line that comes off of there and the other one to the main part of hoses that come off the turbo unter the intake.
