ok i just installed my boost gauge it looks good and it work..lol here is my question. when i first start the motor the gauge goes down to the 10 below the 0 is that normal? and my boost gauge only goes up to 8 psi is the normal for having an air intake and a turbo back exhaust? i ask because i don't think i have a turbo back the dude i got the car from said it is but it just doesn't look like a turbo back to me cat back yes just not the turbo back. now being that i am getting 8 psi is that safe for now on a stock fuel system?
ps i have a fcd on my set up for now and it is an 87 t2 i am talking about

 

ummm....yes all is normal. turbo back could be a turbo downpipe, removered pre-cat to the main cat to the cat-back?

 

from the papers he gave me it says new cat and new custom pipes from the cat back but the dude told me turbo back but it doesn't look like the dp is new! so it looks like i have a cat back but not a turbo back

 

-25 to 0 is where all NA's (& cruising turbos) run.
0 & up is the dark side (boost), a highly addictive & fun zone.

 

so i am wondering why i am reading only 7 psi because i have a turbo back exhaust i had someone who works on rx 7's look at it what could it be?

 

Get a boost controller...

 

that is an option but i thought that with an intake and with a turbo back exhaust i would hit like 12 psi of boost!
