I CAN HEAR IT DUMPING MY BOOST BUT AM UNSURE OF WHAT IS DUMPING THE AIR. and it works as long as i dont switch to my secondary the primary works fine but as soon as i let the secondary come on my primarty boost will only go to 4 psi. also when i park the car the next day it works on the primary again.
any ideas i am extremely lost yhear please help

 

Check your vacuum chambers

 

Check your punctuation. Reading that 1st grade writing hurts my head.

 

Have you used the search button and tried searching, there are hundreds of threads on this problems I'm sure you can find it.

 

thanks guys, thanks adam but im tryin to work on my car not my grammar maybe if u dont know u shouldnt answer maybe u should get a mustang and join that forum then u can fit in with all the ********

 

Check all the vaccum lines. I had a similar problem and had 2 lines crossed.

And yes please learn how to write properly so we can understand what you are asking.

 

Take a look at what is happening and when with the turbo system:

Start by looking at the actuators, solenoids and vacuum lines which control the Charge Control and Turbo Control systems.

 

I actually clicked on your thread with the thought that might be able to help you. I have owned and raced RX7's for nearly 30 years.

Since you don't have the time to write anything that is even slightly readable, you will find that a large number of intelligent people won't bother to try and help you. Those are the people you need. I have solved issues like yours on several cars. I won't be offering you any help (EVER), and I'm sure I'm not alone.
