dual relief valve

[cebulmer1]

i just resently took off my valve for the boost gage...yet black cloud has the plug for the air horn that you can plug the line into...should i do that?? because i lost power when i took off the relief valve...i was pondering doing the air horn plug and putting my valve back on..yet another question came up in my head, will i get accurate readings?? open too any answers and thoughts.

The AIH with the fitting for the boost works like a champ. Easy hook up. I can tell you I had the dual relief valve at first, and I am not a big fan of it. Boost readings were up and down, and in my case it did not prevent the SES light from kicking on.

The AIH plug will give you a much more accurate reading vs. the DRV, I saw in other post that you are considering the MAP Maximizer as well, again, a good bet vs. the DRV.

I just bought the electric fix from spdiesel.com. Same price as the valves and no ses light.

Although both the Dual Relief valve (DRV++) and MAP Maximizer connect to the MAP Line, they serve different purposes.

The DRV keeps you within safe Boost limits 25-27 lbs, and starts opening ~22 lbs, and in a way acts like a small blow off valve.

The MAP Maximizer also fools the MAP sensor but also lets the MAP sensor thinks that full boost has been achieved and allows you to run all the boost you need while keeping a max boost reading to the PCM.

If anyone needs more clarifications, please shoot me an email, or call. I'll gladly go over the details.

The SES light may have been caused by other things. Did you read the codes to figure out why you were getting it?

Yes I did it was an overboost thing. With the DRV in palce the truck would only make about 20-21 PSI, and the boost was erratic as it rose, with the map fix in place, it makes aourd 29-30, and no SES light.

It must have been a bad one, and I would have gladly replaced it for you for free.
