i had a buschur intake and a greddy profec b II boost controller. and yesterday i put my stock airbox back on and the stock boost solenoid and now im only pushing like 8 psi. does anyone have any ideas on why im only pushing 8 psi?

 

When you hooked up the stock solenoid did you use the stock vac hoses that you origianlly took off? And I mean the exact same ones that came on the car from the factory. They have some restrictor pills in them I believe and if you don't use them when you go back to stock it may not work right. Just my idea. Check on that, plus just go over everything and make sure it is all hooked up right.

 

good call on that one, this happened to me, but i could never find the orignal lines again so i bought MBC

 

yea im using the stock lines. but the line that goes to the intake im not using i put a cap on the solenoid and a cap on the intake. so its just the one line that splits into two. plus i was tuned for 22 psi so i dont have that restrictor pill

 

Try taking the cap off, and running the line from the intake to the solenoid. I have no idea if that will help but it is worth a try. That 8 psi is pretty low.

 

i dont have the stock line for that but any line would do right?

 

You're seeing base wastegate pressure, which means the boost system is not functioning. Usually, that's caused by installing the lines improperly - you need the restrictor pills in the right places to hit the right boost.

 

Thanks for the info and Warrtalon i sent you a pm

 

so i took the cap that i put on my stock boost solenoid and i got on it a bit and i pushed 26 psi. im only supposed to be pushing 22 psi. what is going on?

 

If your stock boost lines have been modified, or the pills have been moved, you could buy a new set from the dealer. They should be pretty cheap. Probably around $40.

 

i have the stock lines but if i have the restrictor pill i wont be pushing the 22 psi anymore just stock 19
