I have an MR, Which we all know has the Mitsu Gauge pack, can I tap into that boost line (which is behind the glove box)for my new Defi Boost gauge PSI?
instead of routing one from the engine bay. The mitsu gauge is connected to the FPR line.

 

I would like to know also.

 

Why do you want 2 boost gauges?

 

the mitsu is in bar, I want psi on my steering mount

 

Probably cuz the mitsu piece isnt the most accurate.

 

because if I tap into it and then it doesnt read that accurate, I would have to replace that whole line, or is there a 2 sided tee, instead of the regular 3 end tee

 

It can't be more unaccurate then my Defi gauge that reads 1.5 psi high.

 

no, the defi reads 35psi

 

bump

 

the mitsu guage can be accurate... here's how u can check

- a stock evo boosts X amount -

- drive stock evo on freeway -

- boost in 3rd and 4th gear -

- record guage reading -

i did this and it proved that the stock guage is accurate. before i had a MBC it peaked at 19 then tapperd to 17
