I just bought an A'PEXi 60mm boost gauge, the instructions that came with it says to put the "T" using the (#1) line in this pic. I have seen people using the other vacuum line (#2), also the guy from the shop I got it from told me to use #2.

What is the difference between these two? Should I use 1 or 2?

 

Here is where mine is at:

I don't see two pictures so I'm not sure what you're trying to compare.

 

# 2 is the better choice

look at my posts and you can see threads all about this.

here i found it for you

enjoy reading.

 

use number 2

 

Ahh hell i feel stupid :P

 

I got mine in #2

 

my factory guages from mitsu was "T" into #1

 

never seen this location for a boost gauge before. have you had any problems with it?

 

i have my omori boost gauge on the fpr ( #1) and i have very accurate reading.

 

i also put mine there and i havent had any problems with it

 

number 2, I think it's the FPR line.

 

Do not use #1. That is for the fpr and it will give strange readings some times. That line is hooked to the fpr so it can raise the fuel pressure 1:1 for every psi of boost you are running. It is not a good place to put a boost gauge and can give odd readings sometimes.

 

I have all kinds of #2 here, and it works great.

 

#2!
#1 is through the solenoid and therefore will not always give a reading.

 

why are you always posting in bold now?
