About to install a dual relief valve on my MAP sensor hose, i have a t-fitting that is in the center of the hose already for my boost gauge. Do I want to install the relief valve closer to the turbo (before boost gauge fitting) or closer to the MAP sensor (after boost gauge fitting)? also do I want to to install it close to the boost gauge fitting or should it be a couple of inches away from it??
Thanks in advance!!

 

Why would you want to install one? In essence, you're building in a boost leak.

Simple tuning changes can completely eliminate the need for a map sensor relief.

 

i have a ts 6 pos chip on the way

 

Doesn't matter.

With proper tuning, a relief valve is entirely unnecessary.

 

Use a bosst fooler not relief valve.

so i should install the chip and see if i get a ses light or a defuel at 22psi boost?

 

No, some tuners won't let it defuel, but you won't get anymore boost either. Relief valve just dumps boost. Boost fooler tells the pcm you have lower boost but let you build boost, and yes that means no defueling. Clay at Riffraff Diesel sells a good setup.

I would.

And like the others said.... if anything, get a boost fooler and not a relief valve.

Personally I prefer to take care of the issue in tuning, since it doesn't cost anything, and there's nothing extra to install.

 

Don't mean to hijack but i also like 5 years ago installed one my self "young and dumb" Not knowing what i was doing. I thought it was cool lol . So i want to get rid of it entirely. Prolbem is i now have a map line thats cut in two. What kinda line or hose do i need to replace it. What DIA and rating.

 

So with out posting a new thread and cluttering the board with a very minor question can anyone answer me quick ????????

 

Common 1/4" 30R7 fuel hose will do the job. That's what I have on mine with a boost fooler.

 

THanks Roland i appreciate the info. Big help as i want to replace my cut in half hose. With out posting a new thread and with out hijacking this one can you pm me some info on the Boost fooler ? Whats its purpose? how dose it work? and it this a diy mod? Just curious..... If or when u get time. Thanks again

 

PM sent.
